John the Apostle
John 3:13WEB·traditional attribution

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

Geneva Bible Notes Reformed

Only Christ teaches heavenly things, for no man ascends to heaven except He who came down from it. His birth upon earth was heavenly, not earthly, conceived by the Holy Spirit; and what is proper to His divinity is spoken of the whole Christ, showing He is one Person in whom two natures are united.

John Calvin Reformed

No mortal man by his own power can enter heaven or grasp the mysteries of God; our human understanding is far below Him. But Christ alone, who is heavenly, opens what was closed to all others, and by clothing Himself in our flesh He makes us partakers of those secrets which would otherwise remain hidden.

AI summary

Albert Barnes Presbyterian

No one has gone to heaven and returned qualified to speak of heavenly things, but Christ came down from there. He possesses two natures: His divine nature dwelt in heaven while His human nature walked the earth with Nicodemus, fitting Him alone to reveal God's will to man.
