John 3:11-15

Truly, truly, I say to you, we speak of what we know and testify of what we have seen, and you people do not accept our testimony.

If I told you earthly things and you do not believe, how will you believe if I tell you heavenly things?

No one has ascended into heaven, except He who descended from heaven: the Son of Man.

And just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up,

so that everyone who believes will have eternal life in Him.
