John 3:13-18

13And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.

14And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: 15That whosoever believeth in him should not perish, but have eternal life.

16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

18He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
