I was trying to explain the concept of god and my beliefs in a way that would cover any and every objection, and eventually realized that my belief system relied entirely on presuppositions. Without the presumption that god was real --and the bevy of associated assumptions that formed the core of my belief system-- I had nothing. I kept testing this even after I realized I could not believe in god, and kept coming back to the same conclusion.
Until the day I admitted to myself that I was an atheist, I adamantly avoided anything even remotely anti-JW. Once I felt free of the organization, I dove in. I'm glad I waited, because I did not have to struggle with doubts about whether or not this new information had shaped my point-of-view. There were times when I wondered about a topic or teaching or commentary from the WTS, including one or two things that really made me worry. But I remained loyal and would put those ideas aside. They look very different from the outside!
I have adjusted my views a bit in light of the recognition that much of science (especially at the cutting edge) is well outside of my understanding. I am open to the possibility that a god (or gods) exists. But I have not found one yet that makes sense. The kind of god that explains our world and our universe would likely not really care about us one way or another, aside perhaps from our usefulness as data points, in which case we will never know of its existence. So I don't worry about it.
