If you read any of Paul’s epistles it’s easy to see that he had a one-track mind after he met Jesus Christ. What an encounter he had! You can read about his encounter with Jesus in Acts chapter 9. It wasn’t that Paul was blinded that made the most impact on him, though it certainly got his attention. Paul, after his encounter with Jesus was overwhelmed; not by the situation, not by the circumstance but by Jesus Himself!
Paul initially did not believe that Jesus was the Son of God, but when he met Jesus, that all changed. When Paul met Jesus he had to deal with him the same way everyone does as described by C.S. Lewis in Mere Christianity. This paragraph in Lewis’ magnum opus has been distilled down by many as “liar, lunatic or Lord.” This is how C.S. Lewis describes how people must, or must not, view Jesus:
“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.” This 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. 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 patronising [sic] nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.”
