Do Jehovah’s Witnesses believe that demon possession is possible within their ranks?
This question came about as a result of my answering this question: Do Jehovah's Witnesses believe in exorcisms?
Is it possible for Jehovah’s Witnesses to become possessed by demons (to the exclusion of obsession, oppression, exterior physical pain, infestation or subjection, which are seen as steps towards being truly possessed by a demon) or are they somehow immune to this possibility?
A small percentage in of Christians seem to hold on to this possibility.
Thus my question: What is the teaching of the Jehovah’s Witnesses on this subject matter?
