Ray Stedman’s book Body Life is still in print, and it had much to do with church renewal in the 1970’s. I think that some, unfortunately, missed the whole message of the book and had a particular type of ‘Body Life’ church service that mimicked what took place in Stedman’s church. The Biblical basis of church fellowship throughout the book seems to have been missed and definitely neglected today in many church fellowships.
The other resource I would recommend is Henry and Melvin Blackaby’s A God Centered Church: Experiencing God Together. It parallels but does not repeat what is in Stedman’s book. Together they would remind many in the church that being the church of Jesus Christ is not about playing church.
