John 3:11-15

I tell you the truth, we talk about what we know, and we tell about what we have seen, but you don’t accept what we tell you. I have told you about things here on earth, and you do not believe me. So you will not believe me if I tell you about things of heaven. The only one who has ever gone up to heaven is the One who came down from heaven—the Son of Man. “Just as Moses lifted up the snake in the desert, the Son of Man must also be lifted up. So that everyone who believes can have eternal life in him.
