This book discusses the existence of Satan and his followers and the evil that they produce.

Saint John Chrysostom, the great teacher wrote much on the sleepless enemy of man’s salvation. This book teaches us about this incorporeal force, which because of pride, fell from heaven and due to sheer envy, tempted man to rebel against God. This resulted in a hard and implacable war and an irreconcilable hatred. Saint John teaches us the way in which we should journey in order to avoid his snares and battle the evil. He confronts those who assert that if the devil did not exist, man’s salvation would be easier, and also those who contend that demons are those who govern the human sphere.
