So, this is the message which we have heard from him and are announcing to you: God is light, and there is no darkness in him at all. If we say that we have fellowship with but we walk in darkness then we are lying and are not practising the truth! But if we walk in the light, just as he is in the light, then we have fellowship with each other, and the blood of his son, Jesus, cleanses us from all sin. If we say that we do not have sin, then we lead ourselves astray, and the truth is not in us. If we confess our sins, he is faithful and just so that he might forgive our sins and cleanse us from all unrighteousness. If we say that we have not sinned, then we make him a liar and his word is not in us.
