Dr. Carl Henry wrote in his book, God, Revelation and Authority "Without a doctrine of Angelology, it is impossible to give an adequate account of the world of spiritual relationships and conflicts; spirit intelligences stand in important relationships to God and to each other, but also to man and the world." This book is purposed to help the Christian develop a Biblical world view that includes a doctrine of Angelology. This book will further unveil the goals for Satan's angels, as well as God's angels, which have been given to each of them. Their abilities and work are well documented by certain events that unfolded in history. The culmination of their work is recorded in the Book of Revelation when God brings to a dramatic conclusion Satan's ambitious attempt to remain god over the peoples and nations of the world.
