Mark 2:27-3:4
27
Then he said to them, "The Sabbath was made for man, not man for the Sabbath. 28 So the Son of Man is Lord even of the Sabbath."3
Another time he went into the synagogue, and a man with a shriveled hand was there. 2 Some of them were looking for a reason to accuse Jesus, so they watched him closely to see if he would heal him on the Sabbath. 3 Jesus said to the man with the shriveled hand, "Stand up in front of everyone."4
Then Jesus asked them, "Which is lawful on the Sabbath: to do good or to do evil, to save life or to kill?" But they remained silent.
NIV
Heb 4:8 For if Joshua had given them rest (G2664 katapauo), He would not have spoken of another day after that. 9 So there remains a Sabbath-keeping (G4520 Sabbatismos) for the people of God. 10 For the one, having entered into His rest (G2663), has himself also rested (G2664) from his works, as God from His.
Is not the body of Christ the people of God? And until we are in the grave sleeping, we have not entered His rest, therefore, there is a keeping of His 4th Commandment as He gave it to His people and those of the nations who are called by His Name.
