Demonic oppression can be brought about when an individual is possessed, oppressed, or is in rebellion towards God (sins of the flesh). It takes God's discernment to determine which of these is producing the bondage in an individual's life. The Bible makes it clear that there are demons, or evil spirits, in the world that interfere in people's lives (Ephesians 6:11-19). Evil forces, or powers, influence and control the minds of individuals, bring sickness and cause undesirable behaviour, inability to function normally, and even suicide.
As a result of these forces, people can become a danger to themselves as well as others. What Scripture Says "There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.
For all that do these things are an abomination unto the Lord: and because of these abominations the Lord thy God doth drive them out from before thee" (Deuteronomy 18:10-13). "For we wrestle not against flesh and blood, but against principalities, against powers, against rulers of the darkness of this world, against wickedness in high places" (Ephesians 6:12). "... there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way.... 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" (Matthew 8:28b, 32).
"There came also a multitude out of the cities round about unto Jerusalem, bringing sick folks, and those with which were vexed with unclean spirits: and they were healed every one" (Acts 5:16). "Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envying’s, murders, drunkenness, revelling’s and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God" (Galatians 5:19-21).
