I don't know that God doesn't do anything. I actually believe the opposite, that God is active in my life and is benevolent. I don't have any proof for that, which upsets the scientist in me, but I accept it. There's a feeling within me that there is an omnipotent being who cares about me very deeply and helps me through life. Some people might call that my imagination; some might call it mental illness; some people might call it heartburn. I call it God. It's personal to me, as I can't offer any proof of it. I think it's a positive thing, as I feel urged to care for those less fortunate and to lead a good life, a moral life. I can't say anything about it that will convince a nonbeliever to convert. It's just a feeling that I have strongly within me.
I agree 100% that people have interpreted God's will incorrectly over the years and in some cases have no belief at all, but simply use God as an excuse for all types of destructive behavior. And you're right, a charismatic leader can lead a group of people to ruin and catastrophe. It doesn't change my own personal belief that there is a benevolent omnipotent being who loves me and tries to guide me through life, even though I stumble just about every day. It's infuriating to some people, but please realize that I'm not trying to make anyone else choose my beliefs. I realize that my beliefs are not rational, and not scientifically sound, but I do see good coming from the things that I do, and I positively impact other peoples lives when I try to help them and care for them. It's something I feel led to do, and I won't try to convert anyone, but I will try to help them in any way that I can.
Anyways, this post is getting way off topic. One of my core beliefs is that we'll never know why a perfect God created something, because we'll never fully understand God. The fragments that I am able to glean from texts and from my own experiences, I try to use those to help other people. I'm satisfied with that.
