Deuteronomy makes clear that sabbath-keeping is meant for the welfare of all. God delivered the Israelites out of slavery, so they should observe this freedom with a day of rest. No one should work seven days a week; even slaves and foreigners should be able to rest. Yet human beings can turn even the most liberating religious practice into a life-destroying rule. Jesus does not reject sabbath-keeping, but defends its original life-enhancing meaning. Our worship and our religious way of life are to lead to restoration: the hungry being fed and the sick being healed.
Mark 2:23—3:6
3:1Again Jesus entered the synagogue, and a man was there who had a withered hand. 2They watched Jesus to see whether he would cure him on the sabbath, so that they might accuse him. 3And Jesus said to the man who had the withered hand, “Come forward.” 4Then Jesus said to them, “Is it lawful to do good or to do harm on the sabbath, to save life or to kill?” But they were silent. 5He looked around at them with anger; he was grieved at their hardness of heart and said to the man, “Stretch out your hand.” He stretched it out, and his hand was restored. 6The Pharisees went out and immediately conspired with the Herodians against Jesus, how to destroy him.
