1 John 2:28-3:10
28And now, dear children, continue in him, so that when he appears we may be confident and unashamed before him at his coming.
29If you know that he is righteous, you know that everyone who does what is right has been born of him.
1See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. 2Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears. 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.
