Exorcisms without repentance can backfire badly:
“When an impure spirit comes out of a person, it goes through arid places seeking rest and does not find it. Then it says, ‘I will return to the house I left.’ When it arrives, it finds the house swept clean and put in order. Then it goes and takes seven other spirits more wicked than itself, and they go in and live there. And the final condition of that person is worse than the first.”—Luke 11:24-26
You think the Pelosis’ only have one unclean spirit?
