Lesson 25: 1 John 5:16-18

1 John 5:16-17
If any man see his brother sin a sin
which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it. All unrighteousness is sin: and there is a sin not unto death.
