1 John 1:7-9

New Revised Standard Version Catholic Edition

⁷ but if we walk in the light as he himself 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 that we have no sin, we deceive ourselves, and the truth is not in us. ⁹ If we confess our sins, he who is faithful and just will forgive us our sins and cleanse us from all unrighteousness.
