There are those who have left the JWs and become athiest/agnostic/skeptic. Some would say those people have had their faith in God so shaken by the corrupt, man-made religion of JWs that they have fallen into confusion and need to be shown the "right" way.
That's not how I felt, or why I became one of those "atheist/agnostic/skeptic" types. Here's why I became agnostic: When my examination of JW teachings and practices provided evidence that they were not the right religion, I knew I had to find the right way to worship God. That was my chief concern. So I started re-reading the Bible, just the Bible. Oops...my new-found examination skills found the Bible lacking in certain, uh, "divine" qualities. Hmmm...now what? The Qu'ran? Hmmm...similar problems. Book of Mormon? LOL. What about other religious groups? Loose confederations of Christians? Individuals with religious ideas? Hmmm...all flawed.
What about the alternative, evolution and such? Hmmm...where are all those flaws I was taught to look for?
That's what happened to me. I didn't feel turned off from God because of my JW experience. I was perfectly willing to accept God in my life in whatever manner He would want me to do. Problem is, if you look at any other religion with the same perceptive eye that can tear apart JW theology, you also find problems, inconsistencies, errors, special pleadings, etc.
If I could find a religion that would act as if it really were from a God of love, I might be interested. So far, none have passed the test. I finally decided that any God worth worshipping wouldn't demand worship in the first place. I expect nothing at death. If I get something anyway, I'll call it a lucky bonus, and be all ears for whatever is next.
