John 3:11-13

¹¹Truly, truly, I say to you, we speak what we know, and we testify about what we have seen. Yet you do not accept our testimony.

¹²If I told you about earthly things and you do not believe, how will you believe if I tell you about heavenly things?

¹³No one has ascended into heaven except he who descended from heaven—the Son of Man.
