1 John 1:5–10
5This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all.
6If we say that we have fellowship with him and walk in the darkness, we lie and don’t tell the truth.
7But if we walk in the light as he is in the light, we have fellowship with one another, and the blood of Jesus Christ his Son cleanses us from all sin.
8If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9If we confess our sins, he is faithful and righteous to forgive us the sins and to cleanse us from all unrighteousness.
10If we say that we haven’t sinned, we make him a liar, and his word is not in us.
