In view of the many Satanic agencies and activities abroad today, it seems necessary and imperative to bring to light what the bible teaches on this subject. Demonology is no myth but a reality. At the outset it is essential to point out that in many instances, people are not possessed but oppressed by demons. The present writer does not believe that Christians can be possessed by demons but that all unbelievers are open to demon possession. However some Christians get troubled in mind when they hear about demons, thinking, mistakenly, that they may have one. Oppression is a power coming upon the person from without. Christians can be tormented for a season with periodical attacks from without but such Christians must not imagine that they are possessed by demons. Such experiences are attacks by the enemy of our souls but not possession.
The intelligence of demons
The activities of demons
Their activities manifest themselves in a three-fold manner:
The energies of demons
Not only are demons active, but they are continuously energetic and always destructively so. This may be proven by the means they employ.
The preferences of demons
These spirits abhor disembodiment and they manifest a strong preference for human bodies. Hence ten times we read in the New Testament of persons being demon possessed. Yet when dispossessed by the power of God, they prefer the carcasses of swine to complete disembodiment (Luke 8:32).
The characteristics of demons
These demons differ as much in character as they do in energy and action. The following are some of them:
How can these demons or wicked spirits be dealt with?
Demons should be dealt with in the power of the Holy Spirit and not in the strength of the natural man. There is one outstanding instance in the New Testament (Acts 19:1316) where some tried to cast demons out and got into trouble themselves The Lord has given into our hands certain spiritual weapons to deal with these powers. Above all is the name of Jesus: In My Name shall they cast out demons (Mark 16:17). And they can be subdued by prayer, especially by prayer arid fasting. Satan and his demon hosts are overcome, too, by the blood of the Lamb (Rev. 12:11).
