Spot on!I believe there are two realms of supernatural spirits. One from God and one from Satan.
As I understand it Lucifer had authority over light and he and his demons witness the world. Satan can therefore tell someone what has happened in the past but not the future. His ability with light leads some to see things in the dark that people interperate as UFO's.
Satan with his powers can pass along accurate events that have happened in the past. But he also can predict future events based on current knowledge. After a soothsayer tells you accurate events of the past you are more inclined to believe his future predictions.
Also if your uncle in Cleveland is looking to buy a new truck and has expressed to the dealership that his favorite color as light blue. You talk to a pyschic and she predicts your uncle will show up in a light blue truck, that is information known in the underworld.
I believe demons have the power to implant things into your mind to the point of a person committing crimes or relay some event of the past.
If the devil can get you to doubt God or get you to commit a crime he has done his job.
