I've used this parable a few times but it bears repeating.
Every single time a theist explains how the God/Man relationship is supposed to work, both morally and functionally, it always sounds like me saying I rehydrated a batch of sea monkeys, took one of them off to the side and told him a vague parable about prostitute, a turkey baster, and double sided coin then put him back in the general population, then waited for ten generations of sea monkeys to go by then on one random day dump out their tank and only save the sea monkeys that 3 times a day faced a certain direction their tank and told me how much they like my hair cut and get angry at them that not all of them got it.
That seriously is how God always come across. "Jeez people I told the illiterate goat herders a couple thousand years ago what I wanted, via a flaming bush that told some dude to chisel stuff on a rock that then looked at in a hat through a magic rock beneath a tree on the 3rd Wednesday of the second month of the fourth quarter. Why is this so hard to get?"
