For people who are self-satisfied and indifferent to God, miracles change nothing. They believe they already have wisdom and they reject Jesus. But those who are know they are needy and weary understand the miracles and embrace the wisdom of Jesus teaching. To them Jesus promises rest.
We know we need real rest and we know the answer is Sabbath. But what is the Sabbath? Why does God command it? When do we enjoy it? And how can we rest when so much work remains to be done?
