1st John 5:12

9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.

11 And this is the record, that God hath given to us eternal life, and this life is in his Son.

12 He that hath the Son hath life; and he that hath not the Son of God hath not life.

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

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.
