Many Western Christians have lost their "fight" attitude. There is no ancient sense of ecclesiastical "militancy." Many are oblivious to cosmic war. Too many desert the spiritual battlefield. The US Army is "Transforming." From a present Legacy Force, it will upgrade its near term Interim Force while planning for the year 2016's Objective Force.

Military people will recognize this book's military doctrinal template. Chaplain Vermont serving on active duty, leads the reader through a classic military frame of reference. Military education concentrates on preparation for combat. Does the Church do the same? Army Rangers never leave their battlefield wounded. How appalling that many congregations leave or neglect their wounded.
