"But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin." 1 John 1:7

Repentance is a recurring attitude of the heart that jump-starts waning humility. It doesn't think more highly of itself because it thinks biblically, in a gospel-driven, grace-saturated, God-glorifying mindset that keeps coming to the cross, relying on the shed blood of Christ. Admitting sin and accepting forgiveness. Repentance is walking in the light.
