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 a 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 patronixing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.--C. S. Lewis, Mere Christianity, book II, chapter 3.
In other words, Jesus was not a great moral teacher ... He was God Himself speaking truth into our lives, caring for our hurts, dying on the cross for our sins, and blazing a trail to eternal life by rising again.
