Superstition and mystery surround the subject of demons. The Bible contains no discourses about them. All we can know must be discerned from the handful of incidents in which they were involved.
The New Testament word rendered demon was used by Greeks to denote an inferior deity. The Bible depicts them as members of the spirit world who are evil, operating in conjunction with Satan.
Jesus cast out demons on numerous occasions. Notice a few cases from Mark’s gospel.
Early during His ministry, a man with an “unclean spirit” came to the synagogue at Nazareth where the Lord was teaching. He cried out, “What do we have to do with You, Jesus of Nazareth? Have You come to destroy us? I know who you are—the Holy One of God!” Jesus cast out the spirit to the amazement of the crowd (Mark 1:21-18).
Later in the same chapter, Mark records that Jesus cast out demons, not permitting them to speak, “because they knew who He was” (v. 34). Their knowledge was correct (see James 2:19), but theirs was an endorsement He could certainly do without!
Mark 5 records the case of Legion. This man was possessed by many spirits, hence his name. They made him unusually strong and given to self-abuse, out of his right mind. These, too, confessed Jesus. This case illustrates demons having emotions, desires, and reasoning power. They asked and received permission to leave the man and enter a herd of swine, resulting in the death of the herd.
Mark 9 records the case of a possessed boy. The spirit that tormented him made him mute. It threw him into convulsions and often threw him into fire or water to destroy him. The boy’s father brought him to Jesus’ disciples. The Lord had given them power over unclean spirits (6:7), but they were unable to cast this one out. Evidently, it was particularly strong or strong-willed. Jesus said the problem was the apostles’ lack of faith (Matthew 17:20).
Despite the varied physical effects produced by demon-possession, it is noteworthy that in no case did it cause one to be a sinner.
The prophet Zechariah foretold the day when prophecy and unclean spirits would be removed from the land (Zechariah 13:2). That day was in the era when the fountain for sin was opened for the house of David (v. 1).
Demon-possession corresponded to the time of the establishment of the kingdom of heaven. God allowed it because it provided one more proof of Jesus’ identity. Even critics knew that expulsion required miraculous power. Thus Jesus told them, “If I cast out demons by the Spirit of God, then the kingdom of God has come upon you” (Matthew 12:28).
