The Sabbath is a commemoration of the Creation of the Universe. Read Genesis Chapter 2:1-3. It is for all people. All of mankind. To rest and reflect upon our Creator and His goodness. Satan doesn’t want that. Choose wisely.
1 Thus the heavens and the earth were completed in all their vast array.
2 By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. 3 Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done.
Therefore; the OTHER 6 days were NOT 'holy'; right?
