Phizzy:
Tell us how you felt, going back to Sydney. Did you feel that you had failed in some way ? or that the WT had really failed you, you certainly got no effective support from them. Did you feel a little bit of sadness at how things ahd turned out ?
Yes! I had certain regrets about leaving the town, and was acutely aware of what I could call my weaknesses.
I do not think I blamed the WTS. Its hard to be sure at this distance, but generally I feel I'm responsible for myself, and do not blame others for my failures. (e.g. Right now - as a student, I would not blame the university if I failed a subject. I think that sense of entitlement, as its called these days, is partly responsible for the failure of western civilisation).
The topic you've raised is complex, and it has wide ramifications. but maybe I could respond with this thought. John Bunyan's, The Pilgrim's Progress from This World to That Which Is to Come; Delivered under the Similitude of a Dream, was known to me, and the idea that the Christian life can be full of stumbles. But, if you stumble - you should just pick yourself up, dust yourself down and try again. While I faltered in that assignment, my faith (at the time, did not falter. I was able to keep Jesus as my example.
And I did try again? And, had a happier time in another assignment a little later.
