Basically, the book sums up everything I've ever felt about ministry, and gives awesome insight into how we can actually live out the Kingdom to see better results. If there are about 60% of the people in our country that are uninterested in current church models than we need to figure out what we're going to do about it.
Hugh and Matt don't give a list of what to do - instead they give thought-provoking ways that we can engage our own ministry philosophies and reconcile them to the way that Jesus lived out mission. What does it look like to create community in meaningful ways that attract people to the real Jesus instead of to the pop-culture Jesus that the American church has created?
Anyway, it is a must-read for pastors and even volunteers in ministries, and I dare say that I think every Christian should read this book. It won't take you forever - I read the bulk of it on my flight home from Oralndo - but it will haunt you for a long time after you finish it.
