Keller, like C.S. Lewis, gives us the Bible and Christianity in modern day plain language. So often preachers lose their audience in a kind of Christian-speak. There's none of that here...Only straightforward, intellectual, logical, and biblical exposition that speaks to the average layperson. And always at the heart of it is the Bibles main message...find your security, identity, worth, and purpose in anything but God, and there's no peace to be found. Put God first, and everything else shifts into it's right place.
