But I’d like you to forget the holy water and salt, that is completely unbiblical. the only way to cast demons out is to preach the gospel.
Exorcism died out with the end of the apostolic era.
Exorcism was a ‘sign’ gift given only to Christ, the apostles and maybe a few others. Those gifts are long gone. Exorcists today are all frauds. Even if the demon disappears, they can come back if the person has not beed led to accept Jesus as Lord and Saviour and been baptised with the holy Spirit.
If not, then that person can be compared to an empty house with all the doors and windows wide open; ripe for the picking for demons to come back and make that person worse that before.
Matthew 12:43 * When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none.
12:44 Then he saith, I will return into my house from whence I came out; ***and when he is come, he findeth it empty, swept, and garnished. ***
12:45 Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first.
Her daughter used to practice summoning souls, one of her sons seems to have drug issue but on the other hand I personally think that a large number of physical problems we have has some thing to do with sins and demons . on the other hand there are curses and demonic forces that will be always there to stop her from listening to word of God.
