Evil spirits can oppress people. To oppress means to bear down, come against, or bind from the outside. This oppression is accomplished by evil spirits in various ways. They cause depression, create negative circumstances, and insert wrong thoughts into the mind such as thoughts of suicide, immorality, unbelief, fear, etc.
Demons create satanic circumstances and situations that tempt men to sin:
"How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were OPPRESSED of the Devil; for God was with Him." --Acts 10:38
Demons can also possess human beings. Demon possession is a condition in which one or more evil spirits (demons) inhabit the body of a human being and take complete control of their victim at will. Some people prefer using the word "demonized" rather than possession, but regardless of the term, the possessed person is host to resident demons. "Possession" does not mean a person is not responsible for his own sin. His responsibility rests with the factors that led to his condition.
Possession can happen willingly. A person may desire to be taken over by spirit powers in order to conduct séances, pronounce curses, become a witch or secure some other supernatural power.
Possession can also occur unwillingly. An individual does not ask to be possessed, but through sinful thoughts, actions, or contact with the occult, possession results.
Demonic powers operating in parents and the sins of the parents can affect the next generation.
"Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;" --Exodus 20:5
"Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation." --Exodus 34:7
"Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me," --Deuteronomy 5:9
This accounts for demon possession or oppression of children such as recorded in:
Mark 7:24-30:
24 "And from thence he arose, and went into the borders of Tyre and Sidon, and entered into an house, and would have no man know it: but he could not be hid.
25 For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet:
26 The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter.
27 But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs.
28 And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children's crumbs.
29 And he said unto her, For this saying go thy way; the devil is gone out of thy daughter.
30 And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed."
Mark 9:17-21:
17 "And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit;
18 And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
19 He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.
20 And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.
21 And he asked his father, How long is it ago since this came unto him? And he said, Of a child."
There is also such a thing as demon obsession. This is a condition where one becomes obsessed by an interest in or preoccupation with demons. It is an unusual interest in the occult, demons, and satan, which controls interests and pursuits in a dictating manner. Obsession with demon powers can lead to possession by them.
