Keller's "The Reason for God"

Tim Keller's new book is out. There is also a website devoted to the book, where, among other resources, you can download sermons corresponding to chapters in the book. Here are they are:
-Exclusivity: How can there be just one true religion?
-Suffering: If God is good, why is there so much evil in the world?
-Absolutism: Don't we all have to find truth for ourselves?
-Injustice: Hasn't Christianity been an instrument for oppression?
-Hell: Isn't the God of Christianity an angry Judge?
-Doubt: What should I do with my doubts? (by David Bisgrove)
-Literalism: Isn't the Bible historically unreliable and regressive?
I have listened to a couple of the sermons, but have yet to buy the book. I probably won't get to it for a while but I am sure it will be great. I have read that he endorses some sort of theistic evolution, and the sermon on hell was pretty disappointing, but Tim Keller has been a huge source of insight and encouragement to me. For any pastor wanting to better understand the gospel, its implications, and how to communicate sin to postmodern people, Tim Keller should be on your IPod.
