My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense — Jesus Christ the Righteous One.

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, purifies us from all sin.

And he has given us this command: Whoever loves God must also love his brother.
