If you have struggled with an addictive sin, or are trying to help someone that does, then you know that these sins have great potential to enslave. This book offers various keys to unlock the enslaving shackles. However, understand, there is no master key, only a Master Unlocker. This book strives to be real and practical. It strives to keep the heart and power of the gospel at the forefront. It incorporates modern-day examples, poetry, and action steps. It is researched and nuanced but not scholarly. The chapters and book are intentionally short so it’s not intimidating to pick up and read. This book is written by someone that has fought the gospel-centered war and has experienced much victory by the grace of God and yet knows scars are real and the battle is never over. The book also shows that the author has fought alongside many comrades, both helping and receiving help. In short, the book is real about war and offers help in our continued gospel-centered war. ***** As the title of this book makes clear, a gospel-centered approach is, in the long run, the only effective way to combat sin and addiction. Any resource, like this one by Paul O'Brien, which helps us fight our sinful compulsions by means of the gospel of Jesus Christ is one I recommend. -Dr. Donald S. Whitney, professor of biblical spirituality and associate dean at The Southern Baptist Theological Seminary, and author or Spiritual Disciplines of the Christian Life and Praying the Bible. ***** Gospel-Centered War is for those who struggle with life-dominating sin and for those who counsel them. Instead of simply addressing behavior modification, Paul O'Brien gets to the heart of the matter. This book addresses the issues that provide freedom from destructive, self-defeating behaviors by helping the reader understand how God can change their heart and passions. Read it, devour it, and then be changed from the inside out. -Pastor Mike Wilson, Lincoln Heights Baptist Church, Mansfield, Ohio ***** Paul is a genuine man of faith who has dedicated his life to Jesus and his calling. As a former heroin addict who was mentored by Paul, I had the privilege to witness his passion for Christ and his desire to help people through God’s word. This book shows that same passion. -Ricky Upton, Louisville, KY
