The motive for repentance is not only sorrow for sin but also a sense of the mercy of God in Christ. We have zero motivation to repent, unless we see the mercy of God awaiting us. Not the slap of God, but the embrace of God. Repentance is not just turning from sin, not even that primarily. Repentance is primarily turning to God, moment by moment, because He has promised His mercy to the penitent.
