1 John 3v3-6

Heavenly Father
Give us grace today to remain in you and live pure lives

³ Everyone who has this hope set on him purifies himself, even as he is pure. 
⁴ Everyone who sins also commits lawlessness. Sin is lawlessness. 
⁵ You know that he was revealed to take away our sins, and no sin is in him. 
⁶ Whoever remains in him doesn’t sin. Whoever sins hasn’t seen him and doesn’t know him.
