A number of times as a JW elder I went to homes where the dub thought they had demons they would throw everything they thought might be possesed including pictures, video games, containters etc. etc. the demons never went away. I think the only container that need to be cleaned out was their heads.
Over the past 20 years the borg has discreetly removed the thoughts and notions of demons possesing people and moved the issue to mental problems. Has anyone else noticed that?
