John 3:11-13

¹¹Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen; but you do not receive our testimony. ¹²If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? ¹³No one has ascended into heaven but he who descended from heaven, the Son of man.
