"What, then, about the "hope of righteousness" for which we wait through the Spirit? Notice that it does not say that we through the Spirit hope for righteousness. Rather, we wait for the hope of righteousness by faith, that is, the hope, which the possession of righteousness brings." ~Ellet J. Waggoner
Bear this in mind that while the Sabbath day is the seventh day of the week, the rest, which the Sabbath day brings to view, is continuous. Only those who rest in the Lord all the time keep the Sabbath. When Jesus cried, “It is finished,” He was announcing that through His cross could be obtained the perfect works of God, which were finished from the foundation of the world.
