Exorcism is the practice of evicting demons or other spiritual entities from a person, or an area, that are believed to be possessed.
Unlike the Jewish exorcists, Jesus did not use any mechanical devices or blessed items. He had no need to appeal to the authority of any other spiritual power. He himself was the authority that the demons recognized. And while the exorcists of Jesus’ day had long complicated process to drive demons out, Jesus amazed everyone by simply speaking and commanding demons to leave.
Similarly, in contrast to many modern deliverance ministries, the exorcism process used by Jesus and the apostles was generally very brief and simple.
