3 And everyone who has this hope in him purifies himself, just as that one is pure.
4 Everyone who practices sin also practices lawlessness, and sin is lawlessness.
5 And you know that that one was revealed in order that he might take away sins, and in him there is no sin.
6 Everyone who resides in him does not sin. Everyone who sins has neither seen him nor known him.
7 Little children, let no one deceive you: the one who practices righteousness is righteous, just as that one is righteous.
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.
