“Therefore, it is fitting that the new covenant radically alters the Sabbath perspective. The current believer in Christ does not follow the Sabbath pattern of the people of the old covenant. He does not first labour six days, looking hopefully toward rest. Instead, he begins the week by rejoicing in the rest already accomplished by the cosmic events of Christ’s resurrection. Then he enters joyfully into his six days of labor, confident of success through the victory which Christ already has won.”
~O. Palmer Robertson, Christ of the Covenants
Christ’s first advent brought hope. We joyfully start our week resting in the fulfilled promises of the Messiah, instead of living our week in anticipation of them. This is part of the greatness of the New Covenant.
There is a Sabbath rest still to come that all creation groans for-but it is coming; and we have the work of Christ in his incarnation, death, and resurrection to look back on as the assurance that God will fulfill His promises.
Joyfully look forward on what is already accomplished as the assurance of what is yet still to be accomplished!
