Power over evil spirits

Matthew 8:28-34 And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way.
29 And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
30 And there was a good way off from them an herd of many swine feeding.
31 So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.
32 And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.
33 And they that kept them fled, and went their ways into the city, and told every thing, and what was befallen to the possessed of the devils.
34 And, behold, the whole city came out to meet Jesus: and when they saw him, they besought him that he would depart out of their coasts.

Under the pressure of the Light that Jesus carried with Him, even unclean souls were compelled to acknowledge His presence and His Nature. When they saw Him fear seized them as they knew that their time had come to leave the body that they had occupied. In the same way as mentioned earlier, these had to obey the Divine command.

Earthbound, evil human spirits could from time to time or even permanently occupy the bodies of earthmen and use it, including also the brain. There are many in the lunatic asylums with really nothing wrong with them but this. They crowd out the rightful owner of the physical body.

These are the so-called possessed because their physical bodies have been possessed or taken over by another bodiless human spirit thereby using this body for its own purposes. The time is not far off when this will be widely acknowledged and proper help offered to those afflicted with this problem, setting them free and allowing them to become normal productive human beings.
