In the beginning, God created heaven and earth. At the close of each of the first six days he looked over what he had made and declared it to be good, but on the seventh day God rested, observing a sabbath. So teach the opening lines of the Book of Genesis. The point of the Genesis account is not so much that God created the heavens and the earth – the cosmos. Rather, it is that what was created is indeed good, and further, because we are to imitate the activity of God, we humans are to work only six days and then to observe the sabbath on the seventh – so that we might stop and once a week attend to the source of all.
