John 3:9-13

Nicodemus responded and said to Him, “How can these things be?”

Jesus answered and said to him, “You are the teacher of Israel, and yet you do not understand these things?

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.
