C. S. Lewis, who was a professor at Cambridge University and once an agnostic, understood this trifold issue clearly. He writes: "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."
Then Lewis adds: "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 up with any patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to."
Therefore this is Evidence that Demands a Verdict. Investigate and find the truth, you can empirically. And you can be greatly assisted by the One you are seeking to discover the truth about.
