This is a promise of a future hope that ties us to Jesus' return, the one true Sabbath which we live eternally in His rest. In this "Sabbath rest for the people of God," we strive to enter it so that we do not fall by disobedience. However, we are fallen humans and are called into God's grace when we stumble, because we have a God who knows our weaknesses and "has been tempted as we are, yet without sin." So we learn as followers of Jesus to Sabbath regularly as a future hope that one day, we will eternally rest.
