This is a 2014 book about the danger of Christian organizations drifting away from their stated purpose. It is written almost entirely about para-church organizations and has some application to local churches. It is written from an evangelical point of view so a conservative reader can not expect to see separation from that point of view. For example, Billy Graham, Harold Ockenga, and Andy Stanley are presented as leaders that have remained “mission true.” Typical also is the view that methodology and cultural relevance do not affect one’s core vision. The book is filled with stories and illustrations about groups that that remained true to their vision and groups that have not. In either case the stories are interesting: Harvard University, Anrew Carnegie, Young Life, Buck Knives, and more. At the end of each chapter is a list of principles that should be followed to remain true to one’s vision. These are good. There is also a chapter on governing boards and principles for those on various boards.
