God has made water subject to such natural laws that large ships may sail back and forth across deep oceans and safely reach their destinations. Such is the case with the entire universe. The universe has been created in such a way that it is completely subservient to man’s interests. Man may harness its resources in whatever manner he likes. It is thanks to the serviceability of this world that it has been possible for man to develop glorious civilizations. We assume that the existing structure of the universe is unique and that it has taken its final shape. Yet it could have been created in a variety of other ways. What is truly miraculous is that, out of all the possible alternatives, it has taken a form which is useful to mankind. This is a sign of God which, if given deep consideration, will demonstrate a glorious lesson.
