After thirty sermons in the Sermon on the Mount, the closing verses remind us that it is not only about the teachings but about the Teacher. The Pharisees taught by authority (handed down), but Jesus taught with authority—because he is God, the great “I AM.” The God who gave the law to Moses on Mount Sinai is the Jesus who delivered the Sermon on the Mount. But instead of “stay away from the mountain,” Jesus invites us to come because he is the law and the mediator and the sacrifice.
