As usual, he accurately hits the flaws of liberalism (denying the physical resurrection) and fundamentalism (dividing reality into physical and spiritual). A bit disconcerting that he treats these as twin evils, when the former is far more deadly, but still helpful to sift through fundamentalist critiques.
No time now to pull out the zingers on baptism, purgatory, and the like. One disappointing section taking the liberal view on 3rd world debt, but it only lasted about 5 pages.
One illustration of his really worked: when Paul says we are citizens of heaven, he isn't saying that it is our final destination. He was writing to Philippians, a Roman colony made of Roman citizens, who weren't living in Rome. Their purpose was to instill Roman culture in Philippi - to bring the roman worldview to Philippi. This is what a citizen does. In the same way, we are to bring the lifestyle and worldview of heaven to our world. It doesn't mean we can or should withdraw from the world, but that we are to engage and evangelize the world with heaven's way of life.
