Demonology is the study of demons. Christian demonology is the study of what the  Bible teaches about demons. Closely related to angelology, Christian demonology  teaches us about the demons, what they are and how they attack us. Satan and his  demons are fallen angels, real personal beings who wage war against God, the  holy angels, and humanity. Christian demonology helps us to be aware of Satan,  his minions, and their evil schemes. Here are some important issues in Christian  demonology:

What does the Bible say about  demons? The Bible indicates that the demons are fallen angels – angels who  along with Satan rebelled against God. Satan and his demons now desire to  deceive and destroy all those who follow and worship God.

How,  why, and when did Satan fall from heaven? Satan fell from heaven because of  the sin of pride, which led to his rebellion against God. The actual time of his  fall is not recorded in Scripture. It may have occurred outside time as we know  it, that is, before the creation of time and space.

Why  did God allow some of the angels to sin? The angels who fell and became  demons had a free-will choice to make – God did not force or encourage any of  the angels to sin. They sinned of their own free will and therefore are worthy  of God’s eternal wrath.

Can  Christians be demon possessed? We strongly hold to the belief that a  Christian cannot be possessed by a demon. We believe there is a difference  between being possessed by a demon, and being oppressed or influenced by a  demon.

Is there activity of demonic  spirits in the world today? Considering the fact that Satan “walks about  like a roaring lion, seeking whom he may devour” (1 Peter 5:8)  and knowing that he is not omnipresent, it is logical to assume that he would  send his demons to do his work in this world.

Who or what were the Nephilim? The Nephilim (“fallen  ones, giants”) were the offspring of sexual relationships between the sons of  God and daughters of men in Genesis  6:1-4. There is much debate over the identity of the “sons of God.”.

Many people believe Satan and his demons are only personifications of evil.  Christian demonology helps us to understand the nature of our spiritual enemy.  It teaches us how to resist and overcome the devil and his temptations. Praise  God for the victory over darkness through our Lord Jesus Christ! While the  Christian should not be obsessed with demonology, a clear understanding of  demonology will help calm our fears, keep us watchful, and remind us to stay  close to our Lord Jesus Christ. We have Holy Spirit living in our hearts, and  “greater is He that is in us than he that is in the world” (1 John 4:4).

A key  Scripture related to Christian demonology is 2  Corinthians 11:14-15, “And no wonder, for Satan himself masquerades as an  angel of light. It is not surprising, then, if his servants masquerade as  servants of righteousness. Their end will be what their actions  deserve.”
