THE CHEMISTRY OF LIFE. REVIEW

We usually say atom is the smallest part of matter but scientists have found out that
there are small particles inside atoms. Do you remember their names? Proton, neutron
and electron.

Where are protons?
- Protons are in the nucleus.
Which particles are in the nucleus?
- Protons and neutrons are in the nucleus
Where are electrons?
- They move around, in the orbit.
Do neutrons have charge?
- No, they don’t.
Do protons have charge?
- Yes, they have positive charge.
Do electrons have mass?
- We say they don’t have mass (because their mass is very very small, much
smaller than proton and neutron mass).
Where is the mass of an atom?
- It’s in the nucleus

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.[1] Chemical reactions are studied by chemists under a field of science called chemistry. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz. heat, light or electricity. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions.

The substance/substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.

Reaction EnergyAll chemical reactions are accompanied by a change in energy. Some reactions release energy to their surroundings (usually in the form of heat) and are called exothermic. For example, sodium and chlorine react so violently that flames can be seen as the exothermic reaction gives off heat. On the other hand, some reactions need to absorb heat from their surroundings to proceed. These reactions are called endothermic.

Reactions that proceed immediately when two substances are mixed together (such as the reaction of sodium with chlorine or urea with ammonium chloride) are called spontaneous reactions. Not all reactions proceed spontaneously. For example, think of a match. When you strike a match you are causing a reaction between the chemicals in the match head and oxygen in the air. The match won't light spontaneously, though. You first need to input energy, which is called the activation energy of the reaction. In the case of the match, you supply activation energy in the form of heat by striking the match on the matchbook; after the activation energy is absorbed and the reaction begins, the reaction continues until you either extinguish the flame or you run out of material to react.

There are several differences between a physical and chemical change in matter or substances.

A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
For example, if a piece of paper is cut up into small pieces it still is paper. This would be a physical change in the shape and size of the paper. If the same piece of paper is burned, it is broken up into different substances that are not paper.
Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all. For example, a cup of water can be frozen when cooled and then can be returned to a liquid form when heated.

If one decided to mix sugar into water to make sugar water, this would be a physical change as the water could be left out to evaporate and the sugar crystals would remain. However, if one made a recipe for a cake with flour, water, sugar and other ingredients and baked them together, it would take extraordinary means to separate the various ingredients out to their original form.

Diffusion is a time-dependent process, constituted by random motion of given entities and causing the statistical distribution of these entities to spread in space. The concept of diffusion is tied to notion of mass transfer, driven by a concentration gradient.

The concept of diffusion emerged in the physical sciences. The paradigmatic examples were heat diffusion, molecular diffusion and Brownian motion.

Diffusion - the process by which molecules spread from areas of high concentratiion, to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM

Concentration gradient - a difference between concentrations in a space.

OSMOSIS

Watch this animation of water molecules moving across a selectively permeable membrane. Water molecules are the small blue shapes, and the solute is the green.

The solute is more concentrated on the right side to start with, which causes molecules to move across the membrane toward the left until equilibrium is reached.

Mixture refers to the physical combination of two or more substances the identities of which are retained. Mixtures are either homogeneous or heterogeneous. A homogeneous mixture is a type of mixture which the composition is uniform. A heterogeneous mixture is a type of mixture the composition of which can easily be identified since there are two or more phases present. Air is a homogeneous mixture of the gaseous substances nitrogen,oxygen,and smaller amounts of other substances.Salt,sugar,and many other substances dissolve in water to form homogeneous mixture. Homogeneous mixture are also called solution.

An organic compound is any member of a large class of chemical compounds whose molecules contain carbon.

Carbohydrates: Mainly sugars and starches, together constituting one of the three principal types of nutrients used as energy sources (calories) by the body. Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen.

Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells. Complex carbohydrates are derived from plants. Dietary intake of complex carbohydrates can lower blood cholesterol when they are substituted for saturated fat.

Carbohydrates are classified into mono, di, tri, poly and heterosaccharides. The smallest carbohydrates are monosaccharides such as glucose whereas polysaccharides such as starch, cellulose and glycogen can be large and even indeterminate in length.

Monosaccharides

These are the basic compounds with a cyclic structure consisting of carbon, hydrogen and oxygen in the ratio 1:2:1. 'Mono' refers to single and saccharides means sugar. Glucose, fructose and galactose are types of monosaccharides.

Disaccharides

These carbohydrates mean 'two sugars', which refer to the commonly available types such as sucrose, maltose and lactose. When two monosaccharides bond together by a condensation reaction, they release one molecule of water and a disaccharide is formed. This bond is called a glycosidic bond.


Polysaccharides

These are also called monomers and are composed of thousands of molecules of the basic units of glucose. Carbohydrates stored in the form of starch contain these type of compounds. Amylose, which is a straight chain compound and amylopectin, which is a branched compound, are the most common types of polysaccharides.

Nucleotides

It is another complex carbohydrate which contains many molecules of cyclic sugar. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are complex five sided sugars classified under this category. The difference between RNA and DNA is that the former has one extra hydroxyl group.

All Lipids are hydrophobic: that’s the one property they have in common. This group of molecules includes fats and oils, waxes, phospholipids, steroids (like cholesterol), and some other related compounds.

Fats and oils are made from two kinds of molecules: glycerol (a type of alcohol with a hydroxyl group on each of its three carbons) and three fatty acids joined by dehydration synthesis. Since there are three fatty acids attached, these are known as triglycerides.

The terms saturated, mono-unsaturated, and poly-unsaturated refer to the number of hydrogens attached to the hydrocarbon tails of the fatty acids as compared to the number of double bonds between carbon atoms in the tail. Fats, which are mostly from animal sources, have all single bonds between the carbons in their fatty acid tails, thus all the carbons are also bonded to the maximum number of hydrogens possible. Since the fatty acids in these triglycerides contain the maximum possible amouunt of hydrogens, these would be called saturated fats. The hydrocarbon chains in these fatty acids are, thus, fairly straight and can pack closely together, making these fats solid at room temperature. Oils, mostly from plant sources, have some double bonds between some of the carbons in the hydrocarbon tail, causing bends or “kinks” in the shape of the molecules. Because some of the carbons share double bonds, they’re not bonded to as many hydrogens as they could if they weren’t double bonded to each other. Therefore these oils are called unsaturated fats. Because of the kinks in the hydrocarbon tails, unsaturated fats can’t pack as closely together, making them liquid at room temperature. Many people have heard that the unsaturated fats are “healthier” than the saturated ones. Hydrogenated vegetable oil (as in shortening and commercial peanut butters where a solid consistency is sought) started out as “good” unsaturated oil. However, this commercial product has had all the double bonds artificially broken and hydrogens artificially added (in a chemistry lab-type setting) to turn it into saturated fat that bears no resemblance to the original oil from which it came (so it will be solid at room temperature).

Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.

Biochemistry refers to four distinct aspects of a protein's structure:

Primary structure
the amino acid sequence of the peptide chains.

Secondary structure
highly regular sub-structures , which are locally defined, meaning that there can be many different secondary motifs present in one single protein molecule.

Tertiary structure
three-dimensional structure of a single protein molecule; a spatial arrangement of the secondary structures. It also describes the completely folded and compacted polypeptide chain.

Quaternary structure
complex of several protein molecules or polypeptide chains, usually called protein subunits in this context, which function as part of the larger assembly or protein complex.

Nucleic Acids
DNA and RNA


Living organisms are complex systems. Hundreds of thousands of proteins exist inside each one of us to help carry out our daily functions. These proteins are produced locally, assembled piece-by-piece to exact specifications. An enormous amount of information is required to manage this complex system correctly. This information, detailing the specific structure of the proteins inside of our bodies, is stored in a set of molecules called nucleic acids.

The nucleic acids are very large molecules that have two main parts. The backbone of a nucleic acid is made of alternating sugar and phosphate molecules bonded together in a long chain.

Though only four different nucleotide bases can occur in a nucleic acid, each nucleic acid contains millions of bases bonded to it. The order in which these nucleotide bases appear in the nucleic acid is the coding for the information carried in the molecule. In other words, the nucleotide bases serve as a sort of genetic alphabet on which the structure of each protein in our bodies is encoded.

DNA
In most living organisms (except for viruses), genetic information is stored in the molecule deoxyribonucleic acid, or DNA. DNA is made and resides in the nucleus of living cells. DNA gets its name from the sugar molecule contained in its backbone(deoxyribose); however, it gets its significance from its unique structure. Four different nucleotide bases occur in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

The versatility of DNA comes from the fact that the molecule is actually double-stranded. The nucleotide bases of the DNA molecule form complementary pairs: The nucleotides hydrogen bond to another nucleotide base in a strand of DNA opposite to the original. This bonding is specific, and adenine always bonds to thymine (and vice versa) and guanine always bonds to cytosine (and vice versa).

The double-stranded DNA molecule has the unique ability that it can make exact copies of itself, or self-replicate. When more DNA is required by an organism (such as during reproduction or cell growth) the hydrogen bonds between the nucleotide bases break and the two single strands of DNA separate. New complementary bases are brought in by the cell and paired up with each of the two separate strands, thus forming two new, identical, double-stranded DNA molecules.

RNA

Ribonucleic acid, or RNA, gets its name from the sugar group in the molecule's backbone - ribose. Several important similarities and differences exist between RNA and DNA. Like DNA, RNA has a sugar-phosphate backbone with nucleotide bases attached to it. Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does not contain thymine, instead, RNA's fourth nucleotide is the base uracil (U). Unlike the double-stranded DNA molecule, RNA is a single-stranded molecule. RNA is the main genetic material used in the organisms called viruses, and RNA is also important in the production of proteins in other living organisms. RNA can move around the cells of living organisms and thus serves as a sort of genetic messenger, relaying the information stored in the cell's DNA out from the nucleus to other parts of the cell where it is used to help make proteins.

GOD'S TRUTH AND SCIENCE

God reveals the knowledge of truth through his word in the Bible, so it is not a scientific textbook.
Man needs God to tell him about spiritual things can not be explained or experienced. For this reason God gave us our senses and our mind to observe and work in the physical world.
then this is the realm of science: man's observations of the physical world. Which is supported in Job 5:7.

Understandind God's relationships to truth

God and Science.

A DEFINITION OF SCIENCE

A body of facts that man has gathered by observing the physical universe.

Fact is something that is true.

But What is true? How does one know that a supposes fact is true?

TRUTH: WATH EVERYBODY BELIEVES?Some facts are established according to what everybody does.
The correspondence theory of truth states that the truth or falsity of a statement is determined only by how it relates to the world, and whether it accurately describes (ie, corresponds with) that world.
It is a traditional model which goes back at least to some of the classical Greek philosophers such as Socrates , Platon , and Aristotle . This class of theories holds that the truth or the falsity of a representation is determined solely by how it relates to a reality; that is, by whether it accurately describes that reality.

Doctrine of Humors
The "Doctrine of the Four Humors" dominated "the theory of health". The doctrine taught that four basic elements comprised all matter: fire, earth, water, and air. Each element had two qualities. For example, fire was hot and dry, earth was dry and cold, water was cold and wet, and air was wet and hot. Based on that structure, the human body was believed to have four humors corresponding to these natural elements: blood with air, black bile with earth, yellow bile with fire, and phlegm with water. The Greek physician Galen later added personality types to go with each humor.



It is believed that Hippocrates was the one who applied this idea to medicine. "Humoralism" or the doctrine of the Four Temperaments as a medical theory retained its popularity for centuries largely through the influence of the writings of Galen (131-201 CE) and was decisively displaced only in 1858 by Rudolf Virchow's newly-published theories of cellular pathology. While Galen thought that humours were formed in the body, rather than ingested, he believed that different foods had varying potential to be acted upon the body to produce different humours. Warm foods, for example, tended to produce yellow bile, while cold foods tended to produce phlegm. Seasons of the year, periods of life, geographic regions and occupations also influenced the nature of the humours formed.

The imbalance of humours, or "dyscrasia", was thought to be the direct cause of all diseases. Health was associated with a balance the humours, or eucrasia.The qualities of the humours, in turn, influenced the nature of the diseases they caused. Yellow bile caused warm diseases and phlegm caused cold diseases.

In On the Temperaments Galen further emphasized the importance of the qualities. An ideal temperament involved a balanced mixture of the four qualities. Galen identified four temperaments in which one of the qualities, warm, cold, moist and dry, predominated and four more in which a combination of two, warm and moist, warm and dry, cold and dry and cold and moist, dominated. These last four, named for the humours with which they were associated-- that is, sanguine, choleric, melancholic and phlegmatic, eventually became better known than the others. While the term "temperament" came to refer just to psychological dispositions, Galen used it to refer to bodily dispositions, which determined a person's susceptibility towards particular diseases as well as behavioral and emotional inclinations.

Methods of treatment like blood letting, emetics and purges were aimed at expelling a harmful surplus of a humour. They were still in the mainstream of American medicine after the Civil War.

Although completely refuted by modern science, the theory formed basis of thinking about causes of health problems for more than a thousand years. It was first seriously challenged only just before the 18th century. (this needs expanding)

There are still remnants of the theory of the four humours in the current medical language. For example, we refer to humoral immunity or humoral regulation to mean substances like hormones and antibodies that are circulated throughout the body or we say about blood dyscrasia to refer to any blood disease or abnormality.

The theory was a modest advance over the previous views on human health that tried to explain in terms of the divine. Since then practitioners started to look for natural causes of disease and to provide natural treatments.

The Unani school of Indian medicine, still apparently practiced in India, is very similar to Galenic medicine in the emphasis on the four humors and in the treatments based on controlling intake, general environment the use of purging as a way of relieving humoral imbalances.

TRUTH THAT WORKS
- Ussing the right method, by spteps, to solve a problem.

Doctrine of signatures
As above - so below. To the Ancients this aphorism was not just a metaphor. It represented the centerpiece of mediaeval cosmology. Everything, but everything was governed by the planets and their movements through the heavens. Their inherent qualities were reflected in all animate and inanimate things on earth - stones, minerals, animals, plants and people. As the planets moved along their path through the Zodiac their expressions changed depending on the particular characteristics and elemental quality of the sign through which they were passing. The elements then provided the backdrop to this cosmology. Everything in the Universe was not just ruled by a particular planet but was also perceived as a manifestation of the 5 elements - Spirit (Ether), Fire, Air, Earth and Water - and their respective qualities (i.e. hot and dry, hot and humid, cold and dry, cold and humid). These elements were understood in a spiritual/metaphysical sense, not necessarily in a literal sense.


The basis of this cosmology was formed by the idea that Ether/Spirit permeated everything in existence and was regarded as the prime element, the energy (God) from which all the other elements were formed. The Zodiac then was perceived as a kind of archetypal blue-print through which the elements manifest in the world of matter - which is but a denser reflection of the world of ideas. Thus the nature of a sign was firstly defined by the element it is ruled by, whilst the planets represented the dynamic forces which modify their basic expressions.

TRUTH: REPEATED OBSERVATIONS?
Some people think that ideas are established as true by repeated observations. If phenomenon.

The spontaneous generation of life
" It was common knowledge" that simple organisms like worms, frogs, and salamanders could come from mud, dust, and unpreserved food.


Spontaneous generation or Equivocal generation is an obsolete theory regarding the origin of life from inanimate matter, which held that this process was a commonplace and everyday occurrence, as distinguished from univocal generation, or reproduction from parent.

The theory was synthesized by Aristotle, who compiled and expanded the work of prior natural philosophers and the various ancient explanations of the appearance of organisms; it held sway for two millennia. It is generally accepted to have been ultimately disproven in the 19th Century by the experiments of Louis Pasteur, expanding upon the experiments of other scientists before him (such as Francesco Redi who had performed similar experiments in the 17th century). Ultimately, it was succeeded by germ theory and cell theory.

TRUTH: THAT WICH IS LOGICAL
If it makes sense, or if it can be figured out, they think it is true.
In logic, three kinds of logical reasoning can be distinguished: deduction, induction and abduction.

Deductive reasoning, sometimes called deductive logic, is reasoning which constructs or evaluates deductive arguments. In logic, an argument is said to be deductive when the truth of the conclusion is purported to necessarily follow from or be a logical consequence of the truth of the premises and (consequently) its corresponding conditional is a necessary truth. Deductive arguments are said to be valid or invalid, never true or false. A deductive argument is valid if and only if the truth of the conclusion actually does follow necessarily (or is indeed a logical consequence of) the premises and (consequently) its corresponding conditional is a necessary truth. If the conclusion is false, then at least one of the premises must be false. If a deductive argument is not valid then it is invalid. A valid deductive argument with true premises is said to be sound; a deductive argument which is invalid or has one or more false premises or both is said to be not sound (unsound).

Inductive reasoning, also known as induction or inductive logic, is a type of reasoning that involves moving from a set of specific facts to a general conclusion.It can also be seen as a form of theory-building, in which specific facts are used to create a theory that explains relationships between the facts and allows prediction of future knowledge. The premises of an inductive logical argument indicate some degree of support (inductive probability) for the conclusion but do not entail it; i.e. they do not ensure its truth. Induction is used to ascribe properties or relations to types based on an observation instance (i.e., on a number of observations or experiences); or to formulate laws based on limited observations of recurring phenomenal patterns. Induction is employed, for example, in using specific propositions such as:

This ice is cold. (Or: All ice I have ever touched has been cold.)
This billiard ball moves when struck with a cue. (Or: Of one hundred billiard balls struck with a cue, all of them moved.)
...to infer general propositions such as:

All ice is cold.
All billiard balls move when struck with a cue.

Abduction is a method of logical inference introduced by Charles Sanders Peirce which comes prior to induction and deduction for which the colloquial name is to have a "hunch". Abductive reasoning starts when an inquirer considers of a set of seemingly unrelated facts, armed with an intuition that they are somehow connected. The term abduction is commonly presumed to mean the same thing as hypothesis; however, an abduction is actually the process of inference that produces a hypothesis as its end result. It is used in both philosophy and computing.

TRUE: THAT WHICH IS ACCEPTED BY fAITH?
It has been sail that whatever a person belives to be true will be truth for him. A person acts because of his faith - What he belives.

TRUE: THE WORD OF GOD.
Our God is a God of truth. So says John 14:6 I am ...the truth, then calls the Holy Spirit "Spirit of truth" in John 14:17.

"...our gospel did not come to you in word only, but also in power, and in the Holy Spirit and in much assurance..." 1 Thessalonians 1:5

"All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work." 2 Timothy 3:16-17

"This is my comfort in my affliction, for Your word has given me life." Psalm 119:50
"In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it." John 1:1-5

"And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth." John 1:14

"...the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed...." John 3:19-20

"Your word is a lamp to my feet and a light to my path." Psalm 119:105

"But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God.... Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. ... But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned." 1 Corinthians 2:1-14

"...Jesus Himself drew near and went with them. But their eyes were restrained, so that they did not know Him. And He said to them, 'What kind of conversation is this that you have with one another as you walk and are sad?'
"...they drew near to the village where they were going, and He indicated that He would have gone farther. But they constrained Him, saying, 'Abide with us, for it is toward evening, and the day is far spent.' And He went in to stay with them.
"Now it came to pass, as He sat at the table with them, that He took bread, blessed and broke it, and gave it to them. Then their eyes were opened and they knew Him; and He vanished from their sight." Luke 24:15-17, 28-31

"He opened their understanding, that they might comprehend the Scriptures."

"And the disciples came and said to Him, 'Why do You speak to them in parables?' He answered and said to them, 'Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given. ... Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. And in them the prophecy of Isaiah is fulfilled, which says:

"‘Hearing you will hear and shall not understand, and seeing you will see and not perceive; for the hearts of this people have grown dull. Their ears are hard of hearing, and their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their hearts and turn, so that I should heal them.’

“But blessed are your eyes for they see, and your ears for they hear; for assuredly, I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it." Matthew 13:10-17

"And so we have the prophetic word confirmed, which you do well to heed as a light that shines in a dark place, a until the day dawns and the morning star rises in your hearts; knowing this first, that no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit." 2 Peter 1:19-21

"I now send you, to open their eyes, in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me.'" Acts 26:17-18

"Whatever I command you, be careful to observe it; you shall not add to it nor take away from it." Deuteronomy 12:32

"Every word of God is pure; He is a shield to those who put their trust in Him. Do not add to His words, lest He rebuke you, and you be found a liar." Proverbs 30:5-6
"If anyone adds to these things, God will add to him the plagues that are written in this book; and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and from the things which are written in this book." Revelation 22:18-19

Preach the whole truth - whether or not they listen"I have not shunned to declare to you the whole counsel of God. Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. " Acts 20:28

"He said to me: 'Son of man, I am sending you to the children of Israel, to a rebellious nation that has rebelled against Me; they and their fathers have transgressed against Me to this very day. For they are impudent and stubborn children. I am sending you to them, and you shall say to them, ‘Thus says the Lord God.’ As for them, whether they hear or whether they refuse—for they are a rebellious house—yet they will know that a prophet has been among them."
Ezekiel 2:3-5

"You shall speak My words to them, whether they hear or whether they refuse..." Ezekiel 2:7

"Then He said to me: 'Son of man, go to the house of Israel and speak with My words to them. For you are not sent to a people of unfamiliar speech and of hard language, but to the house of Israel, not to many people of unfamiliar speech and of hard language.... But the house of Israel will not listen to you, because they will not listen to Me.... Moreover He said to me: 'Son of man, receive into your heart all My words that I speak to you, and hear with your ears. And go... and speak to them and tell them, ‘Thus says the Lord God,’ whether they hear, or whether they refuse." Ezekiel 3:7-11

"Therefore prepare yourself and arise, and speak to them all that I command you.

Lead new believers from the "Milk" of the Word to the "Meat"
"...as newborn babes, desire the pure milk of the word, that you may grow thereby, if indeed you have tasted that the Lord is gracious." 1 Peter 2:2

"I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ. I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men?" 1 Corinthians 3:1-2

"For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil." Hebrews 5:12-14

Obey the whole truth
"This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go" Joshua 1:8-9
"Thy word have I hid in mine heart that I might not sin against thee." Psalm 119:11
“If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words...." John 14:23-24

"Therefore lay aside all filthiness and overflow of wickedness, and receive with meekness the implanted word, which is able to save your souls. " James 1:21

"Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience. For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart." Hebrew 4:11-12

"They stumble, being disobedient to the word, to which they also were appointed. But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light; who once were not a people but are now the people of God, who had not obtained mercy but now have obtained mercy." 1 Peter 2:7-10

Standing firm on the Rock
“Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.

“But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand: and the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall. ” Matthew 7:24-27
