Before the beginning of human history Satan and his angels instigated a conflict in the spiritual realm that continues to this very moment. The drama of this spiritual warfare storms across the pages of the Bible from Genesis to Revelation. Mankind was created to resolve this ancient conflict, but Satan and the unseen demon hordes he commands will not suffer defeat without an intense struggle. One tactic Satan employs is the varied facets of demon activity. Demonism has pervaded and plagued man since the fall of Adam.
Demonism blinds unbelievers to the Gospel, distracts believers from the spiritual life, and threatens nations with divine judgment. Those who are ignorant or confused about Satans subtle strategies become easy prey. Critical questions continually arise: How do people become enmeshed in demonism? What is demon influence? Who can be demon-possessed? Is exorcism valid? How can the believer protect himself from demonism? Only the Bible can resolve these questions and eliminate the confusion. Individuals under the influence of demons are pawns in the diabolical cause of Satan. Disaster is their ultimate fate. The Bible emphatically warns believers against courting or consorting with any form of demonism.
