The world and its inhabitants are in profound crisis. Some of the crises are natural while others are supernatural or spiritual. This book concentrates on the spiritual crises that humanity faces and how to tackle them. It is what the author is trying to demonstrate in this fabulous book. The devil is not as weak as some can imagine, he is powerful, and he is active in the world today to steal, destroy, and kill. So, there are excellent reasons to believe in his existence even if some pretend to ignore it. Evil regimes, institutional torture and violence, mass murders, brutal rapes, large-scale drug trafficking, terrorist atrocities, sexual and physical abuse of children, occult activity and satanic rituals are the real works he accomplishes in his mission.
