“For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.” –Exodus 20:11
Exodus 20:11 points us back to creation, back to the institution of the Sabbath,
“By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. 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.” –Genesis 2: 2, 3.
This text reminds us that the Sabbath is not some arbitrary law. It’s establishment was not at Mount Sinai when God gave Moses the Ten Commandments, but rather was a part of God’s original plan before sin ever entered the world. The Sabbath is as Holy as the establishment of unity between one man and one woman at the beginning of time. The commandment is simply a reminder to all mankind to worship the creator on His holy day.
