1 John 3:8-10

8 He that commits sin is of the devil; for the devil sins from the beginning. For this purpose the Son of God appeared, that he might undo the works of the devil.

9 Whosoever is born of God does not commit sin; for his seed remains in him; and he cannot sin, because he is born of God.

10 In this the sons of God are manifest, and the sons of the devil: whosoever does not righteousness and that loves not his brother is not of God.
