The Christian life is a battle, but many believers today don’t realize their involvement in spiritual warfare. Our secular society, characterized by doubt and spiritual skepticism, leaves many Christians embarrassed even to talk about demonic forces of opposition. In order to awaken Christians to the battle around them and prepare them for it, Robert Smart surveys the terrain, identifies the enemy, and conveys defensive and offensive maneuvers for combating Satan. Just as military science combines knowledge of the humanities, natural sciences, applied sciences, and engineering, so this “military textbook” combines knowledge of the Bible, historical theology, contemporary culture, apologetics, practical theology, and biblical counseling. Here is a well-rounded overview of the unavoidable reality of spiritual warfare. Table of Contents: Introduction: The Call to Engage in Spiritual Warfare 1.
