What Is Repentance?

Repentance is more than feeling sorry, and Lutherans describe it with a precision that guards against two common errors. It has two parts: contrition—genuine sorrow over sin, produced by the Law as it exposes us—and faith—which turns from the sin to Christ and trusts his forgiveness. Sorrow without faith is only despair; faith without any sorrow over sin is presumption. True repentance holds both: it grieves the sin and flees to the Savior.

Notice what this rules out on either side. Repentance is not merely a bad feeling, a wave of guilt that changes nothing—“worldly grief produces death,” Paul says, while “godly grief produces a repentance that leads to salvation” (2 Corinthians 7:10). But neither is repentance a work you perform to earn back God’s favor, a penance to pay down the debt. The heart of it is not what you accomplish but where you turn: away from sin and toward Christ. The Greek word means, quite literally, a change of mind—a turning around.

This is also why repentance is not a one-time event you complete and leave behind. Luther opened the Ninety-Five Theses by insisting that the whole life of the believer is to be one of repentance—a daily returning to God. It is not the miserable prelude to the Christian life; it is the ongoing rhythm of it. Each day the Law shows us our sin afresh, and each day faith runs again to the forgiveness held out in the Gospel.

And here is the comfort that keeps repentance from being crushing: it is bracketed by grace on both ends. God’s kindness is what leads us to repentance (Romans 2:4), and God’s forgiveness is what meets us there. “A broken and contrite heart, O God, you will not despise” (Psalm 51:17). Repentance is not you climbing back up to a reluctant God; it is you turning around to find he was already running toward you.
