Like the prophets of old, Jesus possessed authority to speak on behalf of the Divine, but in this case, He was the Divine. He had a greater authority than the Jewish scribes, so they could not conclude that He was simply a good rabbi. He had power over the physical and demonic realm, and they could not conclude that He was simply an earthy king. He is the Sabbath rest foreshadowed from Genesis and in the Law. A rest not captured one day a week or upheld by religious traditions, but a forever rest for the soul!
