1 John 5
16 Ref If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not leading to death. There is a sin leading to death. I don't say that he should make a request concerning this.
17 Ref All unrighteousness is sin, and there is a sin not leading to death.
18 Ref We know that whoever is born of God doesn't sin, but he who was born of God keeps himself, and the evil one doesn't touch him.
