If the devil lives, what form does it take and where would we find it?
A simple invitation to explore the nature of evil
Job 1:7 And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
1 Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
Ephesians 2:2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
Satan and his multitude of devils that follow him are totally evil and more intelligent than men. They exist in another dimension that occupies the same space as the Earth, the spirit world. They are disembodied spirits with no physical bodies and they have telepathic contact to the minds of men. They tempt men do evil and try to deceive men so that men will go to hell. God is allowing them to have this power now to test men to see if they will do evil or not, to see what men are worthy to be angels of God in the afterlife and what men are not worthy of it.
Satan and the devils can manifest themselves as evil thoughts telepathically sent to a person and the evil words and deeds that those thougts can cause a person to say or do. They can manifest themselves as visions of points of light or ghostly images to deceive.
[The poltergeist movement of objects might have something to do with the devil making a person believe that the objects will move, and in response to that belief the objects move; a form of psychokinesis.]
