Thank you for replying Amy, I thought your quotations from the WT literature were excellent examples of the abounding contradictions you find in JW belief, well spotted!
When confronted with these problems, everything to a JW is subsumed under two irrational but foundational anchor points. The first is that the Bible is inerrant and secondly that the governing body of their religion is divinely guided in doctrinal interpretation of scripture.
When contradictions arise the response is not to see them as contradictory but awaiting further "light" to be shed in explanation. However bizarre or paranoid the beliefs, JWs are emotionally committed to them for fear of losing their approval within the their chosen religious community and for the prospect of reward in a future earthly paradise.
