I donate because I think it's a good idea. 10% tithe seems like a nice goal. Along the same lines, the State of Kansas says I can write off up to $6K per year in contributions to my kid's college fund. So $6 a year is now my goal for college funds. Kansas is not demanding 529 contributions, and God isn't demanding charity. I just like it when somebody suggests a number.
And speaking of God... I once had a friend describe himself as an "apathetic agnostic". He was not interested in going to atheist meetings to pick apart and re-assemble a new spirituality based on the Ultimate Truth. He didn't care much about the ultimate truth. God? No God? Shrug either way. That is where I am getting to.
If we can't know the ultimate truth, I think, we should step back and decide from an impartial perspective what the good ideas are. What will make the world a better place?
Deciding that this life doesn't matter because there's a better one we can't see? That's a bad idea. It's been used to justify violence and killing. Don't worry about the war, those soldiers got to go to heaven! Nope.
Teaching people from a very young age that there's a structure and hierarchy to the authority they must blindly follow? That's a very bad idea. That's how powerful people get to abuse their power, husbands get to cheat on their wives, parents get to beat their children.
Using an ancient text to justify arbitrary rules against everything from yoga to tattoos to same-sex relationships? Really terrible idea.
So in the end, belief in a higher power just felt like a bad move. And I stopped going to church. And took it out of my profile. On the other hand, atheist discussions about how we should treat each other had good ideas, with the right motivations.
I realize it's not someplace where I have to pick sides right now and forever, but if there's doubt happening around me, I'm going to pick the side with the least jerks, and not worry about the questions I can never truly answer.
