In the 90's, while on a city bus, I overheard an older lady say she does the things she thinks God wants her to in order to avoid going to "the bad place". I shook my head and thought, "What kind of God could ever send a sweet woman like you to hell and more importantly, why do you choose to believe in such a God"?
We are free to believe in whatever God we want or none at all or that all is God. I just don't see how millions (billions?) can choose a belief system that restricts them, that says you must do this, that you must never do this. Some say that if one doesn't believe in God, all morals go out the window. I disagree, as evidenced by the following quote from Michael Shermer:
"If you agree that, in the absence of God, you would commit robbery, rape, and murder, you reveal yourself as an immoral person, and we would be well advised to steer a wide course around you. If, on the other hand, you admit that you would continue to be a good person even when not under divine surveillance, you have fatally undermined your claim that God is necessary for us to be good.”
What really blows my mind are people who have belonged to the same religion all their lives and say it is the best in the world, without ever giving the other ones (or having none at all) an honest try. It's like Americans saying the U.S. is the best country in the world without ever having been overseas.
