How do people become possessed by a devil?

Most people who are reported to be "possessed" are actually suffering from different mental conditions. Sometimes schizophrenia can cause a person to see things that aren't there, hear voices that tell him/her to do things that would seem unreasonable to the "normal" population and ramble on about his/her imagined world using terms and words that make no sense to the rest of us. Often this behavior becomes violent because the victim believes that some of these imagined entities are trying to harm him/her. When this occurs the individual is often classified as "Paranoid Schizophrenic". In a superstitious, overly religious environment, such a person might be called "possessed", when actually the victim is in need of medication. There are several valuable treatments for schizophrenia. They are quite successful but they involve medical science, not religious fanaticism.

"Being possessed by the devil," was an expression used to refer to people who consistently do things that are bad. This expression is much out of date, and is very seldom used today.

Answer:

There are varying degrees of demonic "possession or oppression". It is brought on by different things.

Biblicaly these are:

1. Generational Curses

2. Inherited traits

3. Involvement with sin

4. A person will open doorways that allows these events.

Being involved in such things a witchcraft, Satanism, Fornication, Adultery will invite demonic beings in. It does not always happen, but does often enough. Satan was called Beelzebub, it means "Lord of the flies, or Lord of the Dunghill". By their personal sins, men and women draw these fallen angels much like a pile of dung draws flies, their acts are unclean and filthy.

Almost all sin in an open doorway for entry of demonic beings. The degree of sin is often in relationship to what you get. "Small sins" such as lying may be grounds for entrance of smaller weaker beings, where such things as murder/abortion or out right witchcraft and Satanism will open much bigger doorways in someone's life.

The early Christians believed that evil spirits or demons often entered humans. In fact they believed that mental illness and even sicknesses were caused by possession by evil spirits. We now know conclusively that mental illnesses and unusual behaviour are not caused by spirits. However, belief in possession by evil spirits has not entirely died out, and a few people sometimes still take part in "exorcisms" to drive out evil spirits.
