The Bible clearly tells us where she received her ability, from the spirit that possessed her. Now Paul and Silas enter the city where this slave girl operates. When Paul cast the demon out, her ability to tell the future was lost. The point we need to not miss is that the fortune telling ability was derived from the demon spirit. When the demon was cast out, the fortune telling ability departed as well.
Psychics claim that their ability is derived from the mind.
They claim that it is an ability resident within all humans, but only used by some. The Bible clearly reveals the truth. Psychics are demon possessed people who do not have a gift, but a demon. And those all humans have the ability to be possessed with a demon, not all of us want one Any deal with the devil is bound to be more than you bargained for. You need to read that again.
