Yochanan 3:11-13

¹¹Most certainly I tell you, we speak that which we know and testify of that which we have seen, and you don’t receive our witness.

¹²If I told you earthly things and you don’t believe, how will you believe if I tell you heavenly things?

¹³No one has ascended into heaven but he who descended out of heaven, the Son of Man, who is in heaven.
