OK, so why did I remain in for forty years? There were times when I had doubts, in fact they kept coming back every few years but I did some extra studying, prayed hard , kept busy and then they went away again.
Like some that you mention, I had been in it for virtually all my life . Although it seemed hard to understand, the idea that the Org was totally wrong was just unthinkable. One would sooner have denied the rising of the sun or the force of gravity than to deny that the Gov Body and anointed were the Faithfull and discreet slave. I blamed myself for having doubts and a faith that was weak at times.
As I got older I became a little less of a WT clone and I realised that our "mother org" got her knickers in a twist sometimes , but I still was committed to staying with it. As far as I knew the concepts of the 'truth' were sound and I believed they were directed by the holy spirit, even if losely ( OK I now it sounds daft now)
If I am honest now, then the pschological reasons of emotional support and a sense of community were also true , and I quite fancied living in Paradise
It took an unexpected jolt to make me wake up and take off the blinkers, then it all just crumbled and I realised that it was Just not true.
