1 John 3:3-6

3And everyone who has this hope in Him purifies himself, just as Christ is pure.1

4Everyone who practices sin practices lawlessness as well. Indeed, sin is lawlessness.2 5But you know that Christ appeared to take away sins, and in Him there is no sin. 6No one who remains in Him keeps on sinning. No one who continues to sin has seen Him or known Him.
