Marching Orders by Dan McGuire applies military strategy to evangelization, framing the mission to spread the Gospel as a form of spiritual combat. Drawing from his experience as a Marine officer, McGuire adapts the “operations order” to equip Christians with faith, reason, and the Holy Spirit in their battle against worldly opposition. Evangelization, he argues, is a universal duty, requiring courage, discipline, and strategic planning. The book provides practical guidance on assessing challenges, leveraging Church resources, and effectively proclaiming the Gospel. With a structured, battle-tested approach, Marching Orders empowers believers to embrace their calling as spiritual warriors.
