A decent enough book. It was, perhaps, less revelatory than Piper may have hoped, at least for me, but I already agreed with him about the importance of thinking (love the Lord your God with all your mind, after all) and the danger of intellectual pride and spiritually dead knowledge. I have seen in my own life the emptiness of head knowledge alone, and have also been guilty of intellectual laziness when I avoided thinking about challenging spiritual truths instead of continuing to grapple with those truths by the light of Scripture. So I agree with Piper that we love God best with heart and mind and soul and strength. Still, for those who struggle with a natural (or learned) antipathy to intellectualism, or those who place their faith in knowledge and understanding (and there are many Christians in both camps), this could well be a much-needed rebuke.

I particularly liked Piper's discussion of reading as thinking, but that's hardly surprising, since that discussion included linguistics, hermeneutics, textualism, and any number of other areas that I find inherently interesting.

All in all, a fine book, though not exactly earth shattering (for me, anyway).
