This was my first free audiobook from christianaudio.com. It's a pretty good book with an interesting premise you probably never thought you'd hear: Christian hedonism. Basically, that our greatest pleasure/happiness/joy is found in God's glory. Even 'present suffering' is endured because we 'await the greater joy'... or something like that. I'm no author, so obviously, the book says it better than I can. Anyway, Piper says that we were created for God's glory, so that is why we find the most pleasure in doing what brings him glory: because it is our purpose. Hmm... maybe reviewing the chapter titles would help me get more out of this... The first half of the book seemed very positive, with lots of examples of how joy and happiness can be seen as results of God's glory. The second half, however, seemed to be an advertisement for missionaries, saying how we should all be missionaries, enduring suffering for the joy we will receive later. Perhaps the book would be better served in two versions or parts: one for the beginning Christian, and one for the die-hard follower of Christ.
The most annoying thing about the book, which was probably accentuated by the audio-ness of it, is that it seemed almost half of the book was biblical references. I guess for a Christian worldview book, that's a good thing, but when you're listening to someone narrate, it's hard to know whether you're hearing the author's words, or a quote, until the 'chapter and verse' is quoted. (Subsequently, if they'd taken every 'chapter' and 'verse' out of the narration, it probably would have shortened the book quite a bit; i.e. "John three sixteen" instead of "John, chapter three, verse sixteen"). As with most nonfiction's, I would probably have gotten a lot more out of the book (as well as some better examples to write a summary that doesn't sound so.... churchy?).
