One thing I miss from my days of being actively religious and attending Christian church every Sunday is that feeling of having all the answers. There was only one question I ever asked in Sunday School that our teacher couldn't answer. I asked one day, "How come there aren't any dinosaurs in the Bible?"
My Sunday School teacher answered, "That is a mystery, God works in mysterious ways," or some pablum like that.
Other than that, my religion had ALLLLLLLLL the answers; and that felt great! Now, I know how much I don't know, and it's uncomfortable.
