I'm listening to John Piper's Desiring God in audiobook. This makes my, I don't know, whatever-th time through.
The dominant thought I'm having this time is about the same thought I've had every time I've read it. It's simply-put.
The book has been through several editions. I think if just one more particular revision could be made, it might well still be serving the church, should the Lord tarry, in another 50, 100 or more years. Do this: edit out every mention of "Christian hedonism," or the like.
Well, Piper could mention the phrase once in the new forward. He could explain how he grew out of it and realized that it (A) was an unredeemable phrase, and that (B) it distracted from his most important and central points, and that (C) his repeated attempts to defend it in the book further undercut the real message of the book.
Piper could mention that he realized that the book had been split between defending how it was really daring and clever of him to use the phrase "Christian hedonism," trying to force readers to embrace the phrase "Christian hedonism," on the one hand, and advocating the Biblical truth of delighting in God, on the other.
Then Piper could say he realized that it is the latter that he really wanted to develop, and that he gladly forsook the former in the interests of that pursuit.
There. One as-yet unpublished writer's opinion.
