Spiritual Warfare is a book written by Richard Ing. It is on a very short list of books I have read in my Christian ministry career that are not totally waste of time. So many Christian books are a totally waste of time, paper and money unless you are an absolute , milk-sucking, spiritual baby.
This, however, is one I have read twice, studied in different times of life, and given out to other people that want wisdom in the area of spiritual warfare. Full of informative insight and recommended prayers, this book is a must read for those growing in the Spirit of God.
