John 3:13-17

And no one hath ascended into heaven, but he that descended out of heaven, even the Son of man, who is in heaven. And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up; that whosoever believeth may in him have eternal life. For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life. For God sent not the Son into the world to judge the world; but that the world should be saved through him.
