Premise #1 = If God does exist, it would be reasonable He would want us to know He exists. Premise #2 = Jesus Christ claimed God the Father sent Him to make Himself known to us. Premise #3 = Jesus Christ said and performed things that no man could say or perform. Premise #4 = Jesus Christ fulfilled predictions about God that no man could fulfill. Premise #5 = Jesus claimed to be God the Son, equal to the Father. Conclusion = Therefore, God exists, and made Himself known to us in the Son, Jesus Christ.

C.S. 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.”
