1 John 3:5-8

3:5 And you know that Jesus was revealed to take away sins, and in him there is no sin. 3:6 Everyone who resides in him does not sin; everyone who sins has neither seen him nor known him. 3:7 Little children, let no one deceive you: The one who practices righteousness is righteous, just as Jesus is righteous. 3:8 The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this purpose the Son of God was revealed: to destroy the works of the devil.
