John 3:14 ASV

¹²  If I told you earthly things and ye believe not, how shall ye believe if I tell you heavenly things?

¹³  And no one hath ascended into heaven, but he that descended out of heaven, 'even' the Son of man, who 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 believeth may in him have eternal life.

¹⁶  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.
