1 John 1:7-9

7 But if we walk in the light, as he is in the light, we have fellowship one with another*, and the blood of Jesus Christ his Son cleanseth 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 is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
