“Sanctifying the Sabbath is part of our imitation of God, but it also becomes a way to find God’s presence. It is not in space but in time, he writes, that we find God’s likeness. In the Bible, no thing or place is holy by itself; not even the Promised Land is called holy. While the holiness of the land and of festivals depends on the actions of the Jewish people, who have to sanctify them, the holiness of the Sabbath, he writes, preceded the holiness of Israel. Even if people fail to observe the Sabbath, it remains holy.”
