Mike Licona is one of my most favorite apologists.
Matt Dillahunty said what would convince him Jesus is God he has no idea, but that if it is true He is morally responsible to make him believe what would be needed to believe. To me that strikes eerily similar to Calvinism. Whereas in Christianity God gives you sufficient grace to have the free choice so your left without excuse for rejecting the evidence that God so aptly provides.
Take this to the extreme. Let's say there are 1 billion things in the universe. Even if Matt knew all 999,999,999 things as to their cause and effect, he would conceivably still hold out for that one last thing required for him to know if God exists. He is basically saying he has to be God to know if God exists. Obviously Matt doesn't know all things and only God could know all things.
This seems arrogant and lacking any ounce of humility.
Matt Dillahunty is under the false impression he lost his faith. Actually, it was never there to begin with, for we are once-saved-always-saved like John 10.28 says those who are born-again "they shall never perish". Matt was never been born-again so whatever he thought was his faith it lacked the depth to truly be a new creation of God in God's eyes. He was basically living a lie. He was living a lie as false Christian and now living a lie as an Atheist. Satan is the father of lies.
