Luke 23.52-54

"This man went to Pilate and asked for the body of Jesus. Then he took it down and wrapped it in a linen shroud and laid him in a tomb cut in stone, where no one had ever yet been laid. It was the day of Preparation, and the Sabbath was beginning."

As we participate by faith through grace in the reconciling work of Christ as our sacrifice for sin, so we will participate in his Sabbath rest from that work. Both his work and his rest are ours through a union with him.

And this union with Christ does not spiritualize away the literal Sabbath hours from creation any more than his death for our sin would mean we no longer live in a literal world of sin. The work of Christ and the rest of Christ does not do away with ours, but sanctifies it, making both holy by the merits of his perfections.

The Sabbath remains a living memorial in time, the seventh-day of each week, for honoring God who created the heavens and the earth in seven literal days (Gen. 2.1-3; Exodus 20.8-11), and for the Sabbath his Son took at the end of his passion week.

Resting with God was typified by in his ceasing his finished work of creation in the beginning. (Gen. 1-2). Being redeemed from the enslavement of sin was typified by his deliverance of Israel from the bondage of slavery in Egypt.

"You shall remember that you were a slave in the land of Egypt, and the Lord your God brought you out from there with a mighty hand and an outstretched arm. Therefore the Lord your God commanded you to keep the Sabbath day." Deut. 5.15

Jesus was, is, and will be our eternal Creator and Redeemer, fulfilling the promises and commands of God in us, that they may be written on the tables of our hearts, in flesh instead of stone. Written they are, to be kept by grace and not ignored, being the treasure of our heart in Christ, out of which flows our thoughts, feelings, and actions.

We keep the Biblical seventh-day Sabbath in the New Covenant by his blood, "in remembrance of him".
