God may exist but is he involved in people's lives and the day to day affairs of humans?
We have all been indoctrinated from early childhood (both JWs & non-JWs) that God is involved in people's lives and day to day affairs of humans and that if it's not God then it's the demons.
However, some of us as we grow older and have observed and experienced life have come to the realization that we were lied to - God (if he exists) is NOT involved in people's lives and day to day affairs of humans.
Once you discover that you were lied to, should you speak out there are those who will accuse you of being mad at, angry with God and bitter.
It frightens people like the person in the OP to acknowledge that God (if he exists) is not involved in people's lives, we are alone. The evidence speaks for itself.
