Albert Mohler mentions that Richard Dawkins "never really takes on a serious theological argument, Orr rightly observes."
Theological "arguments" are, in my experience, of such uniformly low quality that I'm entirely unsurprised that Dawkins simply ignores them.
I am not Dawkins, however, and I'm more than willing to stoop to address theological arguments. What can I say, it's a hobby.
So bring it on. Give it your best shot. Construct your best argument for the existence of God. Email me a link or the whole argument, and I'll publish it along with my analysis of why it fails.
Update: I'll extend this challenge to anyone, subject to my editorial discretion.
