Genesis 3:22 — “The man has become as one of Us, to know good and evil”
When God says in Genesis 3:22 that “the man has become as one of Us, to know good and evil,” He is not announcing that humanity has gained divine wisdom or holiness. Instead, He is declaring that humanity has crossed into a realm that belongs to God alone—the realm of moral authority. Scripture consistently uses the phrase “knowing good and evil” to describe the ability to make independent moral judgments, not the possession of divine insight. For example, Deuteronomy 1:39 describes children as those who “do not know good and evil,” meaning they lack the maturity to make independent moral decisions. Likewise, in 2 Samuel 14:17, the woman of Tekoa praises David as one who can “discern good and evil,” referring to his judicial authority. These passages show that “knowing good and evil” is about claiming the right to decide, not about becoming morally enlightened.
This is exactly what Adam and Eve seized in the fall. Before sin entered, God alone defined what was good (Genesis 1), what was not good (Genesis 2:18), and what was forbidden (Genesis 2:17). But by eating from the tree, they rejected God’s authority and claimed the right to define morality for themselves. This is the tragic fulfillment of the serpent’s promise: “You shall be as gods, knowing good and evil” (Genesis 3:5). They did not become divine; they became self‑authorities, attempting to determine right and wrong apart from God. This moral autonomy is the essence of corruption, because humans now judge good and evil through a fallen nature rather than through God’s holiness. Scripture later describes this condition repeatedly: “Every man did what was right in his own eyes” (Judges 21:25). The fall is therefore not merely the breaking of a rule—it is the birth of human self‑rule.
