God's Book about Demons

The more intently we gaze at our disjointed world, the more it seems that the teachings of the Bible about evil are right on target. What does the Bible teach about it? Among other things, it emphasizes that evil is fostered, engineered, and encouraged by evil masterminds who take great delight in stirring it up and watching it wreak its havoc. Who are these evil masterminds? The Bible calls them demons. Demons are evil angels who sinned against God and who now continually work evil in the world. If these beings-the demons-are real, it would seem to be wise to acquaint ourselves with what they are like so we can be on guard against them and their devices.
