A more sure word of prophecy

God created the world in six days, and rested upon the seventh. Therefore, He declares, “the children of Israel shall keep the Sabbath throughout their generations, for a perpetual covenant.” Exodus 31:16. Those who keep God’s commandments may claim the promises contained in Isaiah 58:11-14. KC 60.5
The instruction given in this chapter is full and decided. Those who refrain from labor on the Sabbath may claim divine comfort and consolation. Shall we not believe God? Shall we not call holy the day which He calls holy?Man should not be ashamed to acknowledge as sacred that which God calls sacred. He should not be ashamed to do that which God has commanded. Obedience will bring him a knowledge of what constitutes true sanctification. KC 60.6
