The Sabbath command in the Ten Commandments is a bridge command of sorts. It’s “bridges” the gap between the first four commandments about maintaining our relationship with God because it recognizes him as God. But it also “bridges” to the second six commands about maintaining our relationships with other people, because it helps us see them not just as cogs in an economic engine, but as full-fledged human beings, made in the image of God, and in need of the rest he designed them to enjoy.
