1 John 5:14,16.   And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: ...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. John 15:7.   If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
