3 All who have this hope in him purify themselves, just as he is pure.
4 Everyone who sins breaks the law; in fact, sin is lawlessness.
5 But you know that he appeared so that he might take away our sins. And in him is no sin.
6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous.
8 The 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.
