As a retired Fort Worth Police Gang Intelligence Sergeant, I highly recommend On Spiritual Combat by my old friend Lt. Col. Dave Grossman and new friend, Adam Davis. I am a tenth degree blackbelt and served as a police officer for thirty-six years with the Fort Worth Police Department, and I have experienced dark times from seeing the violence, death, and depravity on the streets. While we may learn the physical and psychological skills of combat in the military, the police academy, or the dojo, we must also train for the spiritual battlefront. On Spiritual Combat is a strategic book written to strengthen our faith, hope, purpose, and relationships.
--Sergeant Richard M. Morris (FWPD ret.)
Along with Lt. Colonel Dave Grossman, Adam Davis has written a book On Spiritual Combat that has long been needed. It draws from the spring-well of the physical, psychological, and spiritual realms. This book energizes beginners and long-time Christians alike so they may benefit from numerous insights the authors provide through a distinctively biblical approach to overcoming the forces of darkness entrenched around us. On Spiritual Combat is a compilation of weaponry--an impressive synthesis of biblical truths that supply us with the weapons that produce remarkable results when we battle dark forces. On Spiritual Combat is an essential must-read for every believer since it points out what evils we fight against and details how we can emerge victorious.
