9“How can that be?” asked Nicodemus.
10“What! You a teacher of Israel,” exclaimed Jesus, “and yet do not understand this!
11In truth I tell you that we speak of what we know, and state what we have seen; and yet you do not accept our statements.
12If, when I tell you earthly things, you do not believe me, how will you believe me when I tell you of heavenly things?
13No one has ascended to heaven, except him who descended from heaven — the Son of Man himself.
14And, as Moses lifted up the snake in the desert, so must the Son of Man be lifted up;
15so that everyone who believes in him may have eternal life.”
