The Delusion of Belief?

I’ve recently had the pleasure to debate a self-avowed atheist via email. While I’m tempted to post his arguments (without his name attached), they’re a bit elementary. Most of his arguments for atheism consist of simply insulting belief in God’s existence as delusional. He even admitted that labeling Christianity as “delusional” is foundational to his argument, thus making his perspective unworthy of respect. He revels in his ability to use the phrase “fantastically arrogant” so many times in reference to belief in God that it’s become boring. Sounds like a page straight out of Christopher Hitchen’s playbook. He’s even resorted to claiming that a creator would have had to create the creator, and so on. How original. He drops names (philosophers’) like flies, but I wonder just how well-read he is for him to resort to such elementary arguments. What I post here is an argument that I put forth which he insists of sidestepping entirely:

From an atheistic perspective, you believe that all things in the world are governed and caused by the laws of biology, chemistry, and physics. Consequently, nothing that exists can function at all outside of these parameters. If all things in this world are governed only by the laws of biology, chemistry, and physics, then why do you dismiss belief in God as utter nonsense? For anyone to believe in God, such a reaction (the belief itself) must necessarily also be governed and even caused by the laws of biology, chemistry, and physics. You're the one that believes that nothing can be governed by anything beyond these. Do you think it's delusional for a lion to take down a gazelle? Of course not, because it's simply yielding to the laws that dictate its actions. Consequently, you're labeling as delusional literally billions of humans that are simply following these material laws. They apparently have no other choice than to believe, since it's these laws that caused it. And if it's possible to go against these laws, as you prove by your unbelief, then yet again we see the possibility of something beyond these laws at work. Anything that can operate beyond these laws is what we call supernatural, typically performed by what we call the spiritual. This then means that even your unbelief is a spiritual act. How ironic.

I’m presently waiting for his response. I’m sure it’ll be good.
