God wills the good of all. Jesus cures the man so that he may truly enjoy the rest of the Sabbath, knowing that he can now work to his full capabilities. The Jewish leadership somehow, captured the Sabbath. What was meant to be a day of rest, during which people could do good things that they might not have time for during the work days, was surrounded by legalistic decisions as to what people could do or not do on the Sabbath. Instead of being at the service of people, the Sabbath of the Pharisees enslaved them.
Theses are calls to reform and renewal.
Jesus is calling for a renewed understanding of God's loving covenant with His people. To do this, Jesus must confront the Jewish establishment, which is committed to the status quo and the control this gives them of the people. Do we dare to confront the powerful, who enslave others, as for example when the Human Rights Commission of Pakistan in Hyderabad, under the leadership of Shakeel Pathan, confronted the powerful landlords, who keep their Hari workers in their private jails. They were able to expose a serious crime of injustice for the world to see, and to involve many people in the struggle to bring about reform and change. In our own lives such dramatic acts may not always be possible.
