I John 1:7-9
7 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. 8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 9 faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
