Jesus Christ: Liar, Lord, or Lunatic?

“I believe Jesus was a great moral teacher, but I can’t accept His claim to be God.” Have you ever heard a statement like that…or perhaps said something similar yourself?
C.S. Lewis probes the greatest decision of life:

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 the level of a 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 He is 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.

Liar: Jesus knew he wasn’t God, but said so
Lord: Jesus Christ is everything he says he is
Lunatic: Jesus thought he was God, and pretended to be so

Who is the living Son of God to you?
