Many Christians live as though they are effectively alone in the world. However, there is another realm of intelligent life that plays a role in the worldÑangelic beings. This book explores the doctrine of angels and demons, answering key questions about their nature and the implications for ChristiansÕ beliefs and behavior, helping readers see their place in the larger biblical plotline that includes supernatural beings. An understanding of the reality of angels and demons encourages believers to be vigilant in the light of spiritual warfare and to be confident in ChristÕs victory on the cross.
