There are four options open to a person dealing with Jesus. You may consider Him: a legend, a liar, a lunatic, or Lord and God. If He existed, then He’s not a legend. If He’s a liar, that goes against everything else we know about His character. If He’s a lunatic, how to explain the consistency in His message, the constancy of His love? If those options are removed, where does that leave you?
C.S. Lewis, one-time atheist and author of The Chronicles of Narnia, put the dilemma this way:
A man who was merely a man and said the sort of things Jesus said [about Himself] 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 away with any patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to. (Mere Christianity)
Everything the scriptures say about Jesus is all truth or all lie. There is no mix and match theology. Jesus Christ is God or He is nothing. Either accept Him or reject Him, but it must be a complete choice.
