“So you are a teacher of Israel,” said Jesus, “and you do not recognise such things? I assure you that we are talking about something we really know and we are witnessing to something we have actually observed, yet men like you will not accept our evidence. Yet if I have spoken to you about things which happen on this earth and you will not believe me, what chance is there that you will believe me if I tell you about what happens in Heaven? No one has ever been up to Heaven except the Son of Man who came down from Heaven. The Son of Man must be lifted above the heads of men—as Moses lifted up that serpent in the desert—so that any man who believes in him may have eternal life. For God loved the world so much that he gave his only Son, so that every one who believes in him shall not be lost, but should have eternal life. You must understand that God has not sent his Son into the world to pass sentence upon it, but to save it—through him. Any man who believes in him is not judged at all. It is the one who will not believe who stands already condemned, because he will not believe in the character of God’s only Son. This is the judgment—that light has entered the world and men have preferred darkness to light because their deeds are evil. Anybody who does wrong hates the light and keeps away from it, for fear his deeds may be exposed. But anybody who is living by the truth will come to the light to make it plain that all he has done has been done through God.”
“No one has ever gone up into the presence of God except the One who came down from that Presence, the Son of Man. In the same way that Moses lifted the serpent in the desert so people could have something to see and then believe, it is necessary for the Son of Man to be lifted up—and everyone who looks up to him, trusting and expectant, will gain a real life, eternal life.
