8. The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this reason the Son of God was revealed: in order to destroy the works of the devil.
9. Everyone who is fathered by God does not practice sin, because his seed resides in him, and he is not able to sin, because he has been fathered by God.
10. By this the children of God and the children of the devil are evident: everyone who does not practice righteousness is not of God, namely, the one who does not love his brother.
11. For this is the message that you have heard from the beginning: that we should love one another,
12. not as Cain, who was of the evil one and violently murdered his brother. And for what reason did he violently murder him? Because his deeds were evil and the deeds of his brother were righteous.
