Genesis 2:1 Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
[Patriarchs & Prophets pp 307] The Sabbath is not introduced as a new institution but as having been founded at creation. It is to be remembered and observed as the memorial of the Creator's work. Pointing to God as the Maker of the heavens and the earth, it distinguishes the true God from all false gods. All who keep the seventh day signify by this act that they are worshipers of Jehovah. Thus the Sabbath is the sign of man's allegiance to God as long as there are any upon the earth to serve Him.
The fourth commandment is the only one of all the ten in which are found both the name and the title of the Lawgiver. It is the only one that shows by whose authority the law is given. Thus it contains the seal of God, affixed to His law as evidence of its authenticity and binding force. God has given men six days wherein to labor, and He requires that their own work be done in the six working days. Acts of necessity and mercy are permitted on the Sabbath, the sick and suffering are at all times to be cared for; but unnecessary labor is to be strictly avoided.
“Turn away thy foot from the Sabbath, from doing thy pleasure on My holy day; and call the Sabbath a delight, the holy of the Lord, honorable; and ... honor Him, not doing thine own ways, nor finding thine own pleasure.” Isaiah 58:13. Nor does the prohibition end here. “Nor speaking thine own words,” says the prophet. Those who discuss business matters or lay plans on the Sabbath are regarded by God as though engaged in the actual transaction of business.
Genesis 2:3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
May God add His blessing to the study of His word. “Good night” and God bless!
