John 3:15

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

And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:

For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
