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. (1 John 5:16-17) I thought the wages of all sin is death, both physical and spiritual, but this passage says there is a sin unto death and a sin not unto death. What's the difference? Any thoughts?
