Whoever Believes in Jesus Will Have Eternal Life

John 3:12-15

12  If I have told you earthly things, and you believe not, how shall you believe, if I tell you of heavenly things?
13  And no man has ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
14  And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15  That whosoever believes in him should not perish, but have eternal life.
