1 John 3:8-10

8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

9 Whoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.

10 In this the children of God are manifest, and the children of the devil: whoever doeth not righteousness is not of God, neither he that loveth not his brother.
