The universal moral corruption of humanity resulting from the Fall of Adam. Scripture teaches that every aspect of human nature — mind, will, affections, conscience — has been corrupted by sin (Gen. 6:5; Jer. 17:9; Rom. 3:10–18). Total depravity does not mean every person is as wicked as possible, but that no part of a person is untouched by sin's corruption, rendering them unable to save themselves or truly seek God apart from divine grace. It is the diagnosis that makes the gospel necessary. Far from being a counsel of despair, the doctrine of depravity is the foundation of humility: we are worse than we think, which makes grace more glorious than we imagined.
DEPRAVITY, n. A vitiated or corrupt state of moral character; the state of being depraved or corrupted in morals. In theology, the natural or innate corruption of the human heart, which inclines men to evil and disqualifies them for holy obedience, unless renewed by grace. "The total depravity of human nature is a doctrine of great importance in theology."
Modern secular thought rejects the doctrine of depravity entirely, replacing it with the belief that humans are fundamentally good — corrupted only by environment, poverty, or social structures. This inversion explains the failure of utopian politics: if the problem is external, the solution is systemic change; if the problem is internal (the human heart), only regeneration works. The therapeutic culture reduces depravity to dysfunction — to be treated, not repented of. This robs humanity of moral accountability and the gospel of its urgency.
