In a very real sense, every person who denies God is living of borrowed capital. He enjoys living as if the world is filled with morality, meaning, order and beauty, yet he denies the God whose existence makes such things possible. When you start with theism - "in the beginning God"- these destinations make complete sense. When you start with materialism though - "in the beginning, the particles" - that route takes you over a cliff of absurdity and despair.
