Matt. 11:27 is powerful. Here are some of Carson's comments, which in turn reminded me of something Lewis said.
In the words of D.A. Carson:
“…it is astonishing that “no one knows the Father except the Son” – and those to whom the Son reveals the Father (11:27). A claim like that brooks no middle ground: either Jesus was the exclusive revealer of God, or He was a nut. If the former, we must bow to Him, acknowledge His lordship, receive His word of revelation, delight in His truth and in the knowledge of God only He can provide. If the latter, we must dismiss him at once, and entertain no more pious nonsense about Jesus being one good man or one revealer among many.”
In the words of C. S. Lewis:
"I am trying here to prevent anyone saying the really foolish thing that people often say about him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God. That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic—on the level with the man who says he is a poached egg—or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to."
