You know that God is righteous – then you must recognise that everyone whose life is righteous has been begotten by him. Think of the love that the Father has lavished on us, by letting us be called God’s children; and that is what we are. Because the world refused to acknowledge him, therefore it does not acknowledge us. My dear people, we are already the children of God but what we are to be in the future has not yet been revealed; all we know is, that when it is revealed we shall be like him because we shall see him as he really is. Surely everyone who entertains this hope must purify himself, must try to be as pure as Christ. Anyone who sins at all breaks the law, because to sin is to break the law. Now you know that he appeared in order to abolish sin, and that in him there is no sin; anyone who lives in God does not sin, and anyone who sins has never seen him or known him.
