The Sabbath as a Creation Ordinance
“Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but theseventh day is a Sabbath to the Lord your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates. For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.” – Ex. 20:8-11 (ESV)
Sabbath as Imitation of God
First, six days of work followed by a Sabbath day of rest imitates God’s own pattern (Gen. 2:2). Ryken puts it simply: “We are called to work and rest because we serve a working and resting God.” Frame, borrowing from Meredith Kline’s work, offers three categories in which to classify the rest of God: consummation, enthronement, and consecration.
The Sabbath rest of God, foreshadowing Christ’s future rest at the Father’s right hand, also demonstrates Divine enthronement: “God created the heaven and the earth to be his cosmic palace and accordingly his resting is an occupying of his palace, a royal session. The dawning of the Sabbath witnesses a new enthronement of Elohim.” Christ has always reigned as Lord, but now He has new territory over which to rule.
God Blessed the Sabbath
A second creation-based reason to keep the Sabbath commandment is because the Lord Himself “blessed the Sabbath day” (Gen. 2:3a). Chantry ties this to a blessing that falls on those who enter into God’s rest with him. Regardless of whether or not this refers to blessings being bestowed upon Sabbath keepers, the language of the passage does point toward a perpetual Sabbath pattern. In Genesis 1, God’s blessing is given over the fish in the sea, the fowl of the air, and of humans. This blessing is for the ongoing production and multiplication of each group. God likewise blesses the Sabbath day, setting it apart for ongoing observance.
God Sanctified the Sabbath
A third creation-based reason for seeing the Sabbath as a creation ordinance is that God made the Sabbath holy (Gen. 2:3a). This should give us even more reason to strengthen our resolve to keep the Sabbath. “He who is king over all the earth has, by his sovereign right, made the day holy. He devoted one day in each seven to his worship and service. He does not advise or request but decrees that it is so. He who is eternal divided our time and legislated that we give him a day of worship each week.” Because the Lord himself has sanctified, or set apart, one day a week for reflection upon His work, it would be foolish to carelessly disregard such a pattern.
