I am trying to prevent the really foolish thing that people say about Him, “I am ready to accept Jesus as a great moral teacher, but I don’t accept His claim to be God.” A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would be a lunatic on a level with a man who says he is a poached egg or else he would be the Devil of Hell. You must take your choice. Either this man was, and is, the Son of God: or else a madman or something worse… shut him up for a fool… spit at Him and kill Him as a demon… or fall at His feet and call Him Lord and God. But let us not come with any patronizing nonsense about His being a great teacher. He has not left that open to us. He did not intend to.
