Book excerpt: Are evil spirits assigned to geographical areas? The theme of territorial assignment in the demonic kingdom is one rarely touched upon by theologians, making this book unique in the study of spiritual warfare. The book has been edited by C. Peter Wagner, one of the most highly respected of all teachers in this area, and contains contributions from many key church leaders. None of the contributors lay claim to being the final authority on the topics covered but offer their theories and insights regarding spiritual warfare for the reader's consideration. As well as discussing the theoretical principles involved, the book also records the experiences and discoveries made by practioners of strategic spiritual warfare.
