1 John 5:16-18

If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. All wrongdoing is sin, but there is sin that does not lead to death. We know that everyone who has been born of God does not keep on sinning, but he who was born of God protects him, and the evil one does not touch him.
