When I was desperately trying to convince my boyfriend (now husband) that of course there was a god, why can't you just see and believe like the rest of us enlightened JW's, he agreed to study the bible. I remember exactly that episode in whichever publication it was we were studying, about how science hasn't been able to replicate creation and the whole amino acid/atmosphere blurb. I was totally triumphant that I could show him that science couldn't do it so it had to be god. He came back with some extra research that indeed, showed that science is getting closer all the time to (what I just learned was called) abiogenesis. He suggested that maybe with more time they will get all of them. So I learned that all the "closely-held truths" about creation and god can be challenged. The WTBTS will only publish parts of articles that support its position. You won't read that the scientific community are getting closer with each passing year to explaining mysteries that were once thought to be unsolvable, in the pages of an Awake! magazine.
It was probably that first seed of doubt about the dubs that caused me to think that if they weren't actually honest about this, then their other doctrines are open to challenge too. And it followed, for me anyway, that if they don't present the whole story... WHY don't they? What would they possibly have to hide, or to lose, by being open to critical analysis? I mean, the organisation is led by mean who are inspired of god, giving the food at the proper time and such, so it has to stand up to being picked apart by mere humans. I personally found it wasn't, didn't and can't be. Because at each and every point that it looks shaky, that is a point that you just "have to have faith".
