The Meaning of the Fourth Commandment (3) A Memorial and a Sign

This is one of God’s great purposes in creation and in the history of salvation – that people might come to know that he is the Lord of all and that they might give him the glory that is his due. And so, for his people, he gave them a day where work was off-limits and common activities were off-limits so that they might remember and contemplate where they had been before God had rescued them, but also that they might remember and adoringly ponder the awesome power and glory of their God revealed in their rescue.
— Rev. Jerry Hamstra
