Yes. The laws of nature and natural systems are also part of God’s creation.
Man is not a blank slate. He is shaped by the order and the natural laws that God has inscribed in his creation. A Christian does not simply do “whatever he wants”. He knows that he harms himself and damages his environment when he denies natural laws, uses things in ways contrary to their intrinsic order, and tries to be wiser than God, who created them. It demands too much of a person when he tries to design himself from start to finish.
