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.
