1 5 This is the message we have heard from him and proclaim to you, that God is light and in him is no darkness at all. 1 6 If we say we have fellowship with him while we walk in darkness, we lie and do not live according to the truth; 1 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 all sin. 1 8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 1 9 If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness. 1 10 It we say we have not sinned, we make him a lier, and his word is not in us.
