A lot of times our morality tends to dictate our theology. And that is, well, like I said to Sam Harris. I said, Sam, if there was a God, would you have to change your lifestyle? And he said, 'yeah' and I said, 'Well, I think really, Sam, you just don’t want a boss. The bottom line is you don't want a solving God who tells you this is right or this is wrong. And, you want to live a kind of life where you make your decisions rather than God saying this is what I want you to do with your life.
