Everyone who commits sin commits lawlessness, for sin is lawlessness. You know that he was revealed to take away sins, and in him there is no sin. No one who remains in him sins; no one who sins has seen him or known him.
Children, let no one deceive you. The person who acts in righteousness in righteous, just as he is righteous. Whoever sins belongs to the devil, because the devil has sinned from the beginning. Indeed, the Son of God was revealed to destroy the works of the devil. No one who is begotten by God commits sin, because God’s seed remains in him; he cannot sin because he is begotten by God.
I John 3:4-9
