Demons denote unclean or evil spirits; they are sometimes called devils or demoniac beings. They are evil spirits, belonging to the unseen or spiritual realm, embodied in human beings. The Old Testament refers to the prince of demons sometimes called Satan (Adversary) or Devil as having power and wisdom, taking the habitation of other forms such as the serpent (Gen. 3:1). The New Testament speaks of the Devil as Tempter (St. Matt. 4:3) and it goes on to tell the works of Satan, The Devil, and Demons as combating righteousness and good in any form, proving to be an adversary to the saints. Their chief power is exercised to destroy the mission of Jesus Christ. It can well be said that the Christian Church believes in Demons, Satan, and Devils. We believe in their power and purpose. We believe they can be subdued and conquered as in the commandment to the believer by Jesus (St. Mark 16:17). "In my name they shall cast out Satan and the works of the Devil and to resist him and then he will flee (WITHDDRAW) from you."
