For those who accept the account of Jesus written in the New Testament, an honest conclusion must eventually be made from a trilemma of choices as to who Jesus is and how He is represented - He is either a liar, lunatic or Lord. C.S. Lewis popularized this apologetic argument in order to fend off a casual approach to Christianity. The argument is as follows from Lewis' Mere Christianity:
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 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 patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.
We are faced, then, with a frightening alternative. This man we are talking about either was (and is) just what He said, or else a lunatic, or something worse. Now it seems to me obvious that He was neither a lunatic nor a fiend: and consequently, however strange or terrifying or unlikely it may seem, I have to accept the view that He was and is God. God has landed on this enemy-occupied world in human form.
