People like Hitchens are tough cases. Fundamentally (excuse the term) dishonest when it comes to religion, but because they're so intellectually gifted, they like to believe they're applying the same intellectual precision to religion that they apply to other arenas of thought -- but they aren't. Their biases won't allow them to. For someone like Hitchens it would be a horror beyond belief to suspect for even a fraction of a second that God exists. After all, he might require something of him.
That said, I imagine a lot of people pray for Hitchens, and have for years. With God all things are possible.
But what a weapon in God’s arsenal Hitchens would be once his brain (and mouth) was used for truth. So, pray on, friends.
