There are demons. Demons were once angels that Yahweh created. But then these particular angels chose to follow Satan and were kicked out of Heaven. Now Satan and the other fallen angels are on the earth, bringing torment. Many churchgoers do not believe that there are demons; this book will not prove otherwise. Yahweh gives this training plan to prepare His servants on the subject of spiritual engagement based on one prophet, a servant who endured thirty years of novice training.
