Got this idea, (yeah I know it don't happen often) while reading another post, but the bible says at Acts 10:38 NWT (not with truth translation), "namely, Jesus who was from Nazareth, how God anointed him with holy-spirit and power, and he went through the land doing good and healing all those oppressed by the Devil."
Here and other places, disease, ie. seizures, were in fact possessed by demons, that kind of thinking prevades the Watchtower society, in that local elders tell those suffering to pray more, meeting more, d to d more. I am not saying this clearly but, don't they think that spiritual things (ha ha) will in fact heal a person and that this kind of thinking comes from the biblical belief that disease or at least some of it is caused by being possessed by a demon?
Others thought on this will be very much appreciated, as i am getting younger and don't always think, or even think clearly for that matter.
