1 John 3:8-10
1Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was 2to destroy the works of the devil.
3No one born of God makes a practice of sinning, for God's seed abides in him, and he cannot keep on sinning because he has been born of God.
By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, 4nor is the one who 5does not love his brother.
