I John 1:7-9

⁷but 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. ⁸If we say that we have no sin, we are deceiving ourselves and the truth is not in us. ⁹If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
