1 John 3:8-10

8 The sinner is a child of the Evil One; for the Evil One has been a sinner from the first. And the Son of God was seen on earth so that he might put an end to the works of the Evil One.

9 Anyone who is a child of God does no sin, because he still has God's seed in him; he is not able to be a sinner, because God is his Father.

10 In this way it is clear who are the children of God and who are the children of the Evil One; anyone who does not do righteousness or who has no love for his brother, is not a child of God.
