Fairly short easy read, but really packs a wallop. It is either a wake up call to do what you can to resuscitate your church if there's any hope left or the "bad news" that your church is gasping on its death bed. The happy oblivious depicted who sit in your dying church week after week never seeing the decline is an especially startling thing you will recognize as you read. If you have a sneaking suspicion that your church may be in decline, read before it's too late.
I didn't learn anything new from this book. Yes, most churches fail now because of the "keep it the way it is" mentality of the older members. The book really only confirmed that churches must move forward in order to survive.
