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.)
On Spiritual Combat is the most unique guide to preparing for and winning the spiritual battles of life that I have ever read. The old warrior, Dave Grossman, has used his experience and understanding of the Word to write a book that we all need to read and ponder.
—Jerry Boykin, Lt. Gen. US Army (ret.)
Spiritual warfare is so very real, and the enemy is desperately seeking ways to destroy us and our relationship with Jesus. On Spiritual Combat is a great tool that can help equip you for the battle everyday.
—Brian (LTC, Ret, US Army) and Mel Birdwell, authors of Refined by Fire: A Family’s Triumph of Love and Faith
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.
—Henry A. Harbuck (PhD, ThD), president, AEGA Ministries International and Evangel Christian University of America
I am blessed to count Lt. Col. Dave Grossman as both a fellow servant-warrior and dear brother in Christ. Having recommended his book On Combat for many years now, I can give my highest endorsement for his new book, On Spiritual Combat. Just as On Combat is required reading in many police academies, On Spiritual Combat should be required reading for every Christian warrior (and every would-be Christian) and frankly, every warrior’s spouse. We are fighting a very real spiritual war, and it is imperative that we be fully armed and armored to successfully engage and defeat a very real enemy. This book shows us how.
—Lt. Michael “MC” Williams, police officer and chaplain; founder and director, The Centurion Law Enforcement Ministry; past board vice president, Fellowship of Christian Peace Officers–USA
I love this book! On Spiritual Combat left me educated, convicted, illuminated, and inspired. It relays the marching orders Jesus gives to all of us.
—Dave Eubank, Free Burma Rangers missionary
