1 John 5:11-13 KJV

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.
