1 John 3:2-4

New Revised Standard Version Catholic Edition

² Beloved, we are God’s children now; what we will be has not yet been revealed. What we do know is this: when he^[a] is revealed, we will be like him, for we will see him as he is. ³ And all who have this hope in him purify themselves, just as he is pure.

⁴ Everyone who commits sin is guilty of lawlessness; sin is lawlessness.
