1 John 3:8-10

Williams(i) 8 Whoever practices sin belongs to the devil, because the devil has practiced sin from the beginning. This is why the Son of God appeared, to undo the devil's works. 9 No one who is born of God makes a practice of sinning, because the God-given life-principle continues to live in him, and so he cannot practice sinning, because he is born of God. 10 This is the way to distinguish God's children from the devil's children. No one who fails to do right is God's child, and no one who fails to love his brother.
