A more sure word of prophecy

The Sabbath was not for Israel merely, but for the world. It had been made known to man in Eden, and, like the other precepts of the Decalogue, it is of imperishable obligation. Of that law of which the fourth commandment forms a part, Christ declares, “Till heaven and earth pass, one jot or one tittle shall in nowise pass from the law.” So long as the heavens and the earth endure, the Sabbath will continue as a sign of the Creator’s power. And when Eden shall bloom on earth again, God’s holy rest day will be honored by all beneath the sun.“From one Sabbath to another” the inhabitants of the glorified new earth shall go up “to worship before Me, saith the Lord.” Matthew 5:18; Isaiah 66:23. DA 283.2

No other institution which was committed to the Jews tended so fully to distinguish them from surrounding nations as did the Sabbath. God designed that its observance should designate them as His worshipers. It was to be a token of their separation from idolatry, and their connection with the true God. But in order to keep the Sabbath holy, men must themselves be holy. Through faith they must become partakers of the righteousness of Christ. When the command was given to Israel, “Remember the Sabbath day, to keep it holy,” the Lord said also to them, “Ye shall be holy men unto Me.” Exodus 20:8; 22:31. Only thus could the Sabbath distinguish Israel as the worshipers of God. DA 283.3
