1 John 5:16-18

Revised Standard Version

¹⁶ If any one sees his brother committing what is not a mortal sin, he will ask, and God^[a] will give him life for those whose sin is not mortal. There is sin which is mortal; I do not say that one is to pray for that. ¹⁷ All wrongdoing is sin, but there is sin which is not mortal.

¹⁸ We know that any one born of God does not sin, but He who was born of God keeps him, and the evil one does not touch him.
