I read way too much apologetic literature, of both the Christian and the Muslim kind. It’s always hard to be confident I’m getting a representative sample; after all, I also ignore a lot that seems boring to me when I flip though a few pages. Still, I’ll risk a broad-brush comparison.
The Christian stuff I run into tends to be either not overly concerned with the Bible, or, if it’s fundamentalist in character, will often at least gesture toward detailed reasons why the Bible is completely trustworthy and so forth. There are lots of books out there that purport to demonstrate that the Bible is the Word of God. As a connoisseur of “loony books” and a fan of pseudoscience, I find these very entertaining.
You have to be impressed by it. A billion Muslims, and for most of them, it would almost never occur to question whether an almost incomprehensible mishmash is divine. That’s strength in a faith.
