5 This is the message that we have heard from him and are proclaiming to you: God is light, and in him there is no darkness at all. 6 If we say that we have fellowship with him and walk in darkness, we are lying and are not practicing the truth. 7 But 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 cleanses us from every sin.
8 If we say that we have no sin, we are deceiving ourselves, and the truth is not in us. 9 But if we confess our sins, he is faithful and just to forgive us our sins and cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him out to be a liar, and his word is not in us.
