Fall of man - a starting point

Here are some suggestions for you to think through as "starting points" for approaching the question of "the fall of man". The suggestions are brief but hopefully you will be encouraged to follow up and learn more.

Genesis 3

Now the serpent was more crafty than any other beast of the field that the LORD God had made. He said to the woman, "Did God actually say, 'You shall not eat of any tree in the garden'?" And the woman said to the serpent, "We may eat of the fruit of the trees in the garden, but God said, 'You shall not eat of the fruit of the tree that is in the midst of the garden, neither shall you touch it, lest you die.'" But the serpent said to the woman, "You will not surely die. For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil."

So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate, and she also gave some to her husband who was with her, and he ate. Then the eyes of both were opened, and they knew that they were naked. And they sewed fig leaves together and made themselves loincloths.

And they heard the sound of the LORD God walking in the garden in the cool of the day, and the man and his wife hid themselves from the presence of the LORD God among the trees of the garden. But the LORD God called to the man and said to him, "Where are you?" And he said, "I heard the sound of you in the garden, and I was afraid, because I was naked, and I hid myself." He said, "Who told you that you were naked? Have you eaten of the tree of which I commanded you not to eat?" The man said, "The woman whom you gave to be with me, she gave me fruit of the tree, and I ate." Then the LORD God said to the woman, "What is this that you have done?" The woman said, "The serpent deceived me, and I ate."

The LORD God said to the serpent, "Because you have done this, cursed are you above all livestock and above all beasts of the field; on your belly you shall go, and dust you shall eat all the days of your life. I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel." To the woman he said, "I will surely multiply your pain in childbearing; in pain you shall bring forth children. Your desire shall be for your husband, and he shall rule over you." And to Adam he said, "Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, 'You shall not eat of it,' cursed is the ground because of you; in pain you shall eat of it all the days of your life; thorns and thistles it shall bring forth for you; and you shall eat the plants of the field. By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return."

The man called his wife's name Eve, because she was the mother of all living. And the LORD God made for Adam and for his wife garments of skins and clothed them. Then the LORD God said, "Behold, the man has become like one of us in knowing good and evil. Now, lest he reach out his hand and take also of the tree of life and eat, and live forever--" therefore the LORD God sent him out from the garden of Eden to work the ground from which he was taken. He drove out the man, and at the east of the garden of Eden he placed the cherubim and a flaming sword that turned every way to guard the way to the tree of life.

Romans 5:6-21

For while we were still weak, at the right time Christ died for the ungodly. For one will scarcely die for a righteous person--though perhaps for a good person one would dare even to die -- but God shows his love for us in that while we were still sinners, Christ died for us.

Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God.
For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.

Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned-- for sin indeed was in the world before the law was given, but sin is not counted where there is no law.

Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come. But the free gift is not like the trespass. For if many died through one man's trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. If, because of one man's trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.

Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous.

Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.

Easton Dictionary on the fall of man

An expression probably borrowed from the Apocryphal Book of Wisdom, to express the fact of the revolt of our first parents from God, and the consequent sin and misery in which they and all their posterity were involved.
The history of the Fall is recorded in Gen. 2 and 3. That history is to be literally interpreted. It records facts which underlie the whole system of revealed truth. It is referred to by our Lord and his apostles not only as being true, but as furnishing the ground of all God's subsequent dispensations and dealings with the children of men. The record of Adam's temptation and fall must be taken as a true historical account, if we are to understand the Bible at all as a revelation of God's purpose of mercy.
The effects of this first sin upon our first parents themselves were
(1.) “shame, a sense of degradation and pollution;
(2.) dread of the displeasure of God, or a sense of guilt, and the consequent desire to hide from his presence. These effects were unavoidable. They prove the loss not only of innocence but of original righteousness, and, with it, of the favour and fellowship of God. The state therefore to which Adam was reduced by his disobedience, so far as his subjective condition is concerned, was analogous to that of the fallen angels. He was entirely and absolutely ruined” (Hodge's Theology).
But the unbelief and disobedience of our first parents brought not only on themselves this misery and ruin, it entailed also the same sad consequences on all their descendants.
(1.) The guilt, i.e., liability to punishment, of that sin comes by imputation upon all men, because all were represented by Adam in the covenant of works (q.v.). (See IMPUTATION.)
(2.) Hence, also, all his descendants inherit a corrupt nature. In all by nature there is an inherent and prevailing tendency to sin. This universal depravity is taught by universal experience. All men sin as soon as they are capable of moral actions. The testimony of the Scriptures to the same effects is most abundant (Rom. 1; 2; 3:1-19, etc.).
(3.) This innate depravity is total: we are by nature “dead in trespasses and sins,” and must be “born again” before we can enter into the kingdom (Joh_3:7, etc.).
(4.) Resulting from this “corruption of our whole nature” is our absolute moral inability to change our nature or to obey the law of God.
Commenting on Joh_9:3, Ryle well remarks: “A deep and instructive principle lies in these words. They surely throw some light on that great question, the origin of evil. God has thought fit to allow evil to exist in order that he may have a platform for showing his mercy, grace, and compassion. If man had never fallen there would have been no opportunity of showing divine mercy. But by permitting evil, mysterious as it seems, God's works of grace, mercy, and wisdom in saving sinners have been wonderfully manifested to all his creatures. The redeeming of the church of elect sinners is the means of 'showing to principalities and powers the manifold wisdom of God' (Eph_3:10). Without the Fall we should have known nothing of the Cross and the Gospel.”
On the monuments of Egypt are found representations of a deity in human form, piercing with a spear the head of a serpent. This is regarded as an illustration of the wide dissemination of the tradition of the Fall. The story of the “golden age,” which gives place to the “iron age”, the age of purity and innocence, which is followed by a time when man becomes a prey to sin and misery, as represented in the mythology of Greece and Rome, has also been regarded as a tradition of the Fall.
