Ok Bennett, I see where you're coming from. For me, the book does have the effect of making me question certain practices and realize that so much of what we do (in my church) is based on tradition and not necessarily scripture. But, it doesn't compell me to abandon the current assembly and start from scratch. Rather, it compels me to be a proponent for change, with regard to the things that don't add to the spiritual growth of the body. Granted, there are things that we do that don't fit the mold of scripture but are still instrumental to the growth of the body. For example, the men of the church have gotten together to go bowling in the past. There is no scriptural precedent, but I see the importance of it. Our brothers bonded, and more importantly, the younger guys felt like a part of the entire unit. The end result, over time, was that there was more overall church participation on the part of all men.
So, from the perspective of instigating change, I feel this is a good book.
