1 John 5:16-18

New Revised Standard Version Catholic Edition

¹⁶ If you see your brother or sister^[a] committing what is not a mortal sin, you will ask, and God^[b] will give life to such a one—to those whose sin is not mortal. There is sin that is mortal; I do not say that you should pray about that. ¹⁷ All wrongdoing is sin, but there is sin that is not mortal.

¹⁸ We know that those who are born of God do not sin, but the one who was born of God protects them, and the evil one does not touch them.
