1st John 5:16

13 These things have I written unto you, that ye may know that ye have eternal life, [even] unto you that believe on the name of the Son of God.

14 And this is the boldness which we have toward him, that, if we ask anything according to his will, he heareth us:

15 and if we know that he heareth us whatsoever we ask, we know that we have the petitions which we have asked of him.

16 If any man see his brother sinning a sin not unto death, he shall ask, and [God] will give him life for them that sin not unto death. There is a sin unto death: not concerning this do I say that he should make request.

17 All unrighteousness is sin: and there is a sin not unto death.

18 We know that whosoever is begotten of God sinneth not; but he that was begotten of God keepeth himself, and the evil one toucheth him not.

19 We know that we are of God, and the whole world lieth in the evil one.
