Don't give up on God just because the JWs let you down.
That's been tough for me to do. I was born into the JWs and I was associated with them for over twenty years, till I was about 23. I left them almost 20 years ago, but I never considered joining another religion. So the only God that I've ever known was Jehovah God, of the JW religion.
While I still tend to believe in something higher, possibly a supreme being, I'm not convinced that any ONE religion on earth can explain who or what that being is. And if they cant explain the who or what, they certainly cant say well, "This is God's master plan."
There are just too many religions, non-Christian as well as Christian and too many Bible translations and interpretations. And there are too many wars and hatred / bigotry in the name of religion.
Has anyone ever asked themselves these questions: If there really is a God that cares about us, wouldnt he have ensured that we would all be following the same loving and peaceful path to him? And why would a perfect God have allowed all the religious confusion that we have on the earth today?
