Good and Evil

The distinction between good and evil is foundational to biblical ethics and creation theology. Creation is declared good by God (Gen. 1:4, 10, 12, 18, 21, 25, 31); the fall introduces evil not as a co-eternal principle competing with God but as the corruption of what God made good through the creature's disobedience. The tree of the knowledge of good and evil (Gen. 2:9, 17) stands at the center of the garden as the boundary of human authority — the divine prerogative of determining what is good is not transferred to humanity by right but seized in rebellion. The result is the confusion of good and evil that prophets lament: "Woe to those who call evil good and good evil" (Isa. 5:20). Moral discernment — the capacity to distinguish good from evil — is itself a gift: Solomon prays for "an understanding mind to govern your people, that I may discern between good and evil" (1 Kgs. 3:9), and Christian maturity involves having "powers of discernment trained by constant practice to distinguish good from evil" (Heb. 5:14). The NT's ethical imperatives consistently call for active pursuit of good and avoidance of evil (Rom. 12:9; 1 Thess. 5:21–22; 1 Pet. 3:11), culminating in the final separation at the last judgment (Matt. 25:31–46).
