I’m trying here to prevent anyone from saying the really silly 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’s the one thing we mustn’t say. A man who was merely a man and said the sort of things Jesus said wouldn’t be a great moral teacher. He’d either be a lunatic – on a level with the man who says he’s a poached egg – or else he’d 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 don’t let us come with any patronising nonsense about His being a great human teacher. He hasn’t left that open to us. He didn’t intend to.
