Our modern Western world is deeply confused about what is good and what is evil. We know little about angels and demons, though the Scriptures we purport to believe have much to say about them. We blur the distinction between God and the devil. And we are paying for it. Denial of reality does not change reality. Drawing from Scripture, history, and his own experiences as a missionary and a military chaplain, Harold Ristau helps Christians develop a biblical understanding of our spiritual vulnerability in both "ordinary" life, such as personal temptation, and "extraordinary" situations such as demonic oppression and possession. He takes us beyond theory, where many other resources stop, laying out practical tools to equip us for our own personal battles and steps to take to protect ourselves and others from the evil forces at work in our world. And he lays out an effective, proven process for mature ministers and clergy to follow when performing an exorcism. There is much more to the struggles we face in life than meets the eye. If you want to be prepared for the battles that lie ahead, this book is your grounded, thorough, and hope-filled guide to ministering to the demonically oppressed or possessed.
