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. 6 If we say we have fellowship with him while we walk in darkness, we lie and do not live according to 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 all sin. 8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness. 10 If we say we have not sinned, we make him a liar, and his word is not in us.

Chapter 2

1 My little children, I am writing this to you so that you may not sin; but if any one does sin, we have an advocate with the Father, Jesus Christ the righteous; 2 and he is the expiation for our sins, and not for ours only but also for the sins of the whole world.
