3we declare to you what we have seen and heard so that you also may have fellowship with us; and truly our fellowship is with the Father and with his Son Jesus Christ. 4We are writing these things so that our joy may be complete.
5This is the message we have heard from him and proclaim to you, that God is light and in him there is no darkness at all. 6If we say that we have fellowship with him while we are walking in darkness, we lie and do not do what is true; 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 deceive ourselves, and the truth is not in us. 9If we confess our sins, he who is faithful and just will forgive us our sins and cleanse us from all unrighteousness. 10If we say that we have not sinned, we make him a liar, and his word is not in us.
