If we’re going to have a truly open society, we have to learn how to be public about our deepest faith beliefs, and yet to do so in a way that’s respectful to others and promotes peace.  So how do you talk about God and God’s existence? One way to talk about this with more reflection is not to ask, “Does God exist?” but to ask, “How do you know whether God exists?” I don’t think there’s any more brilliant answer to the question, “How can we know whether God exists?” than in Romans 1. Paul actually gives four answers, all at once. He says, 1) we can know God, 2) we do know God, 3) we don’t know God, and 4) we can truly know God.
