1 John 5:16-18

If anyone sees a fellow believer committing a sin that doesn’t lead to death, he should ask, and God will give life to him — to those who commit sin that doesn’t lead to death. There is sin that leads to death. I am not saying he should pray about that. All unrighteousness is sin, and there is sin that doesn’t lead to death. We know that everyone who has been born of God does not sin, but the one who is born of God keeps him, and the evil one does not touch him.
