This work distinguishes three levels of spiritual warfare: ground-level spiritual warfare, concerned with the casting out of demons; occult-level spiritual warfare, which deals with opposition to occult practices; and strategic-level spiritual warfare, which addresses territorial spirits. Indicating strategies for combating the rulers of darkness, this book tackles certain key themes: the spiritual dimension of world evangelism, the various questions of territorial spirits, the equipment needed by spiritual warriors, naming and mapping the powers, the rules for taking cities for Christ, and the pitfalls of spiritual warfare. Each chapter is full of stories and anecdotes. The book draws upon the author's knowledge of Argentina and China, and uses illustrations from all over the world. It is published in conjunction with Prayer Shield.
