But the creed of liberty means nothing if it is only our own liberty that excites us. - Carl Sagan

If the general picture of an expanding universe and a Big Bang is correct, we must then confront still more difficult questions. What were conditions like at the time of the Big Bang? What happened before that? Was there a tiny universe, devoid of all matter, and then the matter suddenly created from nothing? How does that happen? In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from. And if we decide this to be unanswerable, why not save a step and decide that the origin of the universe is an unanswerable question? Or, if we say that God has always existed, why not save a step and conclude that the universe has always existed?

Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe. I mean the real universe. All those light-years. All those worlds. I think of the scope of your universe, the opportunities it affords the Creator, and it takes my breath away. It’s much better than bottling Him up in one small world. I never liked the idea of Earth as God’s green footstool. It was too reassuring, like a children’s story...like a tranquilizer. But your universe has room enough, and time enough, for the kind of God I believe in.

By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.
