1 John 1:7-9

7But 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, purifies us from all sin.

8If we claim to be without sin, we deceive ourselves and the truth is not in us.

9If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
