A few weeks back, theologian, author and blogger Randal Rauser had a pop at me. We have previously had a few cross-posts and whatnot, and even debated on US radio/Reasonable Doubts podcast on the subject of the Nativity, which can be found here. Luke, a theist who regularly comments here,, also comments at Rauser’s blog, and I got into a revived debate about libertarian free will and the Kalam.
