Where did sin come from?
Question 6002
If God is good and created everything, then where did sin come from? This question has puzzled believers and sceptics alike for centuries. It touches on some of the deepest mysteries of theology: the problem of evil, the nature of free will, and the character of God Himself. Scripture does not give us a philosophical treatise on the origin of evil, but it does give us enough to understand how sin entered God’s good creation.
Sin’s Origin in the Angelic Realm
Before sin ever touched humanity, it had already appeared in heaven itself. The prophet Ezekiel, in a passage addressed to the “king of Tyre” but clearly describing a reality beyond any human monarch, gives us a glimpse into the fall of Satan: “You were the signet of perfection, full of wisdom and perfect in beauty. You were in Eden, the garden of God… You were blameless in your ways from the day you were created, till unrighteousness was found in you” (Ezekiel 28:12-15).
Here was a creature of astonishing beauty and wisdom, created perfect, who somehow became corrupted. Isaiah 14:12-14 adds further detail, again in a passage that moves beyond its immediate historical referent: “How you are fallen from heaven, O Day Star, son of Dawn!… You said in your heart, ‘I will ascend to heaven; above the stars of God I will set my throne on high… I will make myself like the Most High.'” The root of sin, even in heaven, was pride. It was the creature wanting to be like the Creator, the finite aspiring to the place of the Infinite.
This is sobering. Sin did not originate in some dark corner of the universe but in the very presence of God, in a being who had every advantage, every blessing, every reason to remain faithful. And yet pride found a foothold.
Sin’s Entry into Humanity
Genesis 3 records the tragic moment when sin entered the human race. The serpent, identified later in Scripture as Satan himself (Revelation 12:9; 20:2), approached Eve with a question designed to create doubt: “Did God actually say, ‘You shall not eat of any tree in the garden’?” (Genesis 3:1). Notice the subtle distortion. God had said they could eat from any tree except one. The serpent made it sound as though God was withholding good things from them.
Eve corrected him, but then the serpent moved from doubt to direct contradiction: “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” (Genesis 3:4-5). The same temptation that had corrupted Satan was now offered to humanity. You can be autonomous. You can be your own god. You do not need to trust what God has said.
And Eve, seeing that the tree was good for food, a delight to the eyes, and desirable for making one wise, took and ate. Then she gave some to Adam, who was with her, and he ate too. In that moment, everything changed. Sin had entered the human race, and through Adam it would spread to every one of his descendants.
Did God Create Sin?
Here we must be careful. Scripture is emphatic that God is not the author of sin. “God cannot be tempted with evil, and he himself tempts no one” (James 1:13). “This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all” (1 John 1:5). God is holy, utterly set apart from sin, and He cannot be blamed for its existence.
And yet God, in His sovereignty, permitted sin to occur. He created beings with genuine freedom, angels and humans alike, knowing that some would misuse that freedom. Why? Scripture does not fully answer that question, but it does show us that God has a plan to bring greater glory out of the tragedy of sin than would have existed without it. The cross of Jesus, where God’s justice and mercy meet in breathtaking display, reveals depths of divine love that unfallen creatures might never have known.
As Joseph said to his brothers who had sold him into slavery, “You meant evil against me, but God meant it for good” (Genesis 50:20). God does not cause sin, but He sovereignly works even through sin to accomplish His purposes.
Sin’s Spread to All Humanity
Paul explains the universal reach of Adam’s sin in Romans 5:12: “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.” There is debate about exactly how Adam’s sin affects his descendants, but the result is clear: every human being born in the ordinary way inherits both the guilt and the corruption of Adam’s fall. We are not sinners because we sin; we sin because we are sinners. The disease is in the bloodline.
This is why we need a second Adam. What the first Adam lost, Jesus came to restore. “For as in Adam all die, so also in Christ shall all be made alive” (1 Corinthians 15:22). Sin entered through one man’s disobedience; salvation comes through one Man’s perfect obedience.
“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.” Romans 5:12
