1 John 3:3-10

3All who have this hope in him purify themselves, just as he is pure. 4Everyone who sins breaks the law; in fact, sin is lawlessness. 5But you know that he appeared so that he might take away our sins. And in him is no sin.

6No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him. 7Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God.

10This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.
