KJV_Cambridge(i)
14 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
15 And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
16 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.
