"Most of the ten Commandments begin with the same words: “You shall not,” but right in the heart of the law, we find the fourth commandment introduced with the word “Remember.” Q: Why is this one different?
A: God was commanding His people to call something to memory that existed but had been forgotten.
Genesis describes the origin of the Sabbath in these words: “Thus the heavens and the earth, and all the host of them, were finished. And on the seventh day God ended His work which He had done. … Then God blessed the seventh day and sanctified it” (Genesis 2:1–3).
Q: Which day did God bless and sanctify?
A: The seventh day.
Q: How was it to be kept holy?
A: By resting.
Q: Could any of the other six days be kept holy?
A: No.
Q: Why?
A: Because God commanded work on those days, not rest."
