I found this book while searching for books about "delight" and, although it wasn't exactly what I'd set out to look for, I was intrigued by it. Chances are, I would disagree with the theology of most of these authors' churches. For one thing, there's a pretty hefty representation of female pastoring here, and that's not something I consider biblical. Yet despite the signals that I would likely find fundamental disagreements with their theology, when it comes to the topic of the book itself, the content is remarkably solid.
The tone of it is a little hard to describe. In some ways it feels more like it came out of a psychology department than a theology department -- yet not in a way that comes across as wishy-washy or "psychobabble." More like it's focused more heavily on people than on doctrines -- which is a pretty good summary of the point of the book, I think.
Don't get me wrong; the book never suggests that doctrine doesn't matter. The message here, though, is that the heart of ministry is supposed to be relationship -- relationship between the ministers and those they're ministering to and, ultimately, relationship between them and God. There's a refreshing emphasis here on relationship-building, and on building our ministries to serve the needs of those we're pursuing relationship with, in contrast to the all-too-popular approach of sort-of seeking relationships in order to serve the ministries we've built. The entire book is a passionate, creative reminder to get back to the foundations of what makes ministry ministry.
(The same principles all apply to whole-church ministry, as well.)
