There are either two options if you discuss this in philosophy. The man claiming to be the Son of God was either a fullblown nutcase or he actually was/is the Son of God. There is no in between, no middle ground. What that had to teach me was useless.C. S. Lewis, one of the greatest writers on Christianity wrote that there were three options: Jesus was either a liar, an insane man, or the Son of God. He chose Son of God. And so do I.
