From C.S. Lewis’ Mere Christianity:
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 patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.
Christianity stands or falls upon who Jesus is. Out of context the above quote may seem a little harsh; I don’t mean to post it as such. What I intend to say is this: read the gospels. Look at the audacious claims that Jesus makes about himself. He can’t be a good teacher if he was a flat-out liar. If Jesus really is who he said he was then we have to live with the idea that he has the right to make claims upon our life. If he really is the resurrected Lord, he is worthy to be worshiped. If he isn’t, if he’s still a tomb in Palestine, then he was one of the most infamous liars in history and should be laughed at as a fraud and a failure.
