A beginning, and its answer
The First Sin
The first sin is the moment a good creation is fractured: a whispered doubt, a forbidden fruit, and eyes opened to shame. Everything that follows in Scripture, including the coming of Christ, answers this rupture.
“And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.”Genesis 3:6
The first
The first. God had given the man one prohibition in a garden of abundance: "of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die" (Genesis 2:17). Into this comes the serpent, "more subtil than any beast of the field," with a question that twists God's word: "Yea, hath God said, Ye shall not eat of every tree of the garden?" (Genesis 3:1). He follows with a flat denial and a slander of God's motives: "Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods" (Genesis 3:4-5). The woman sees that the tree is good for food, pleasant to the eyes, and to be desired to make one wise, "and she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat" (Genesis 3:6). At once "the eyes of them both were opened, and they knew that they were naked" (Genesis 3:7). They sew fig leaves, hide from God, and shift the blame. The fellowship is broken.
What it means
What it means. The first sin reveals what sin always is: distrust of God's word and grasping for what He has not given. It begins not with an act but with a doubt, "hath God said," and a lie about God's goodness. The fall shows sin's swift consequences: shame where there had been openness, hiding where there had been fellowship, blame where there had been love. Paul makes the first sin the hinge of human history: "by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned" (Romans 5:12). We are not merely imitators of Adam but implicated in Adam; the whole race stands under the fracture that began in the garden. This is why the human problem is not fundamentally ignorance or circumstance but a broken relationship with God, and why no self-improvement can undo it. The first sin establishes the deep need that the rest of the Bible answers, the need for a rescue we cannot perform for ourselves, the need for a second Adam.
How it points to Christ
How it points to Christ. Because sin and death entered by one man, salvation comes by one man. Paul sets Adam and Christ side by side: "For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous" (Romans 5:19). Where the first Adam grasped at being like God, the last Adam, "being in the form of God, thought it not robbery to be equal with God," yet humbled Himself and became obedient unto death (Philippians 2:6-8). Where Adam failed in a garden with a tree, Christ prevailed in a garden of agony and on the tree of the cross. "For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive" (1 Corinthians 15:21-22). The first Adam was made a living soul; "the last Adam was made a quickening spirit" (1 Corinthians 15:45). The disaster of the first sin meets its answer in the obedience of the Son.
Questions people ask
What was the first sin, exactly?
Adam and Eve ate from the one tree God had forbidden, the tree of the knowledge of good and evil (Genesis 3:6). At its root the sin was distrust of God's word and grasping for what He had not given.
Why do we suffer because of Adam's sin?
Romans 5:12 teaches that through one man sin and death entered the world and passed to all. Scripture presents the whole race as implicated in Adam, which is why we need a new representative, the second Adam.
How does Christ undo the first sin?
By His obedience where Adam disobeyed. Romans 5:19 says that as many were made sinners by one man's disobedience, many are made righteous by the obedience of one. In Christ what was lost in Adam is restored and more.
