It is wise to avoid summoning demons. Demons, once invited, may be disinclined to leave.
I managed to get “in the habit” of using a Ouija board years ago. The darn thing became stronger the more I used it. It wasn’t too long before I could make the thing move quite effortlessly by myself.. It hated my husband and adored me.At first I treated it as a game ,but after having used it for a while,it became pretty apparent who was using whom. Finally had friends who refused to visit ,if we were going to bring it out. They saw first hand ,some of the really malevolent things that began happening in our home. Never again.You can chose to believe in them or not. But I will never ,in ignorance bring one into my home again.They are not toys and should not be sold as such.
Those parents surrounded her with prayers day and night until she was able to function again. She managed to function in the world, although in a different way from her real self. You could tell that she still had a demon or two with her because she would talk to them when she thought no one was around.
I brought her to live with me when she was 87. Twice she physically attacked me. The first time, I was able to subdue her. The second time I came face to face with the last demon. It was taking a last stand for her body. I saw it and will never forget it. I invoked the name of Jesus and demanded that it leave my Mother and go back to the pit of hell, in the name of Jesus. From that time until she died a year later, my Mom was back.
Nobody can tell me that demons are not real. I am of sound mind and body and I know what our family went through. I also know how it started. DO NOT FOOL WITH A OUIJA BOARD!
