1 John 5:16-18

If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this. All unrighteousness is sin, and there is a sin not leading to death. We know that no one who is born of God sins; but He who was born of God keeps him, and the evil one does not touch him.
