Question
What was the fall of man? (Adam and Eve's sin in Genesis 3)
Analysis
What happened
The temptation follows a pattern the Bible returns to often: the serpent first sows doubt about God's word ('Did God actually say…?'), then flat denial ('You will not surely die'), then a false promise ('you will be like God'), Genesis 3:1–Genesis 3:5. Eve sees the fruit is desirable and eats; Adam, with her, does the same (Genesis 3:6). Immediately something breaks: they feel shame, cover themselves, and hide from God (Genesis 3:7; Genesis 3:8). God's response is both judgment and mercy, He names the consequences (pain in childbirth, hard toil, and a return to dust in death, Genesis 3:16; Genesis 3:19) and removes them from the garden and the tree of life (Genesis 3:23; Genesis 3:24). The story explains the world everyone experiences: good, because God made it so, yet marred by sin, suffering, and death.
Its reach, and the first gospel
The New Testament treats the fall as a turning point for the whole human race. 'sin entered the world through one man, and death through sin, so also death was passed on to all men' (BSB, Romans 5:12; Romans 5:19), the root of what theologians call original sin, the reason 'in Adam all die' (1 Corinthians 15:22). But Genesis 3 also contains the Bible's first glimmer of the gospel (often called the protoevangelium): God tells the serpent that the woman's offspring will crush its head, though it will strike his heel (Genesis 3:15), read across Scripture as the first promise of a Redeemer who would undo the fall. So the fall sets up the whole story the Bible then tells: a rescue that comes to completion in Christ, the 'last Adam' (1 Corinthians 15:22; Romans 5:19).
