The regularities in nature, simply by being regularities, call for explanation. There are only two ways in which we could, with any plausibility, try to explain them. One way would be to suppose that they are imposed on the world by God. The other would be to suppose that they reflect the presence of laws of nature, conceived of as forms of natural necessity. But the only way of making sense of the notion of a law of nature, thus conceived, is by construing a law as the causing of the associated regularity, and the only remotely plausible account of such causing would be in terms of the agency of God. So, by whichever route, we are led to the conclusion that the regularities are brought about by God. So the presence of the regularities in nature provides us with a strong case for accepting the existence of God.
