3. And everyone who has this hope fixed on Him purifies himself, just as He is pure.
4. Everyone who practices sin also practices lawlessness; and sin is lawlessness.
5. You know that He appeared in order to take away sins; and in Him there is no sin.
6. No one who abides in Him sins; no one who sins has seen Him or knows Him.
7. Little children, make sure no one deceives you; the one who practices righteousness is righteous, just as He is righteous;
8. the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.
