Little children, let no man deceive you: he that does righteousness is righteous, even as he is righteous. He that commits sin is of the devil; for the devil sins from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. Whosoever is born of God does not commit sin; for his nature remains in him: and he cannot sin, because he is born of God. In this the children of God are manifest, and the children of the devil: whosoever does not righteousness is not of God, neither he that loves not his brother. (1 John 3:7-10)
