In Deuteronomy God promises to raise up a prophet like Moses, who will speak for God; in Psalm 111 God shows the people the power of God’s works. For the church these are ways of pointing to the unique authority people sensed in Jesus’ actions and words. We encounter that authority in God’s word, around which we gather, the word that prevails over any lesser spirit that would claim power over us, freeing us to follow Jesus.
21Jesus and his disciples went to Capernaum; and when the sabbath came, he entered the synagogue and taught. 22They were astounded at his teaching, for he taught them as one having authority, and not as the scribes. 23Just then there was in their synagogue a man with an unclean spirit, 24and he cried out, “What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are, the Holy One of God.” 25But Jesus rebuked the spirit, saying, “Be silent, and come out of him!” 26And the unclean spirit, convulsing him and crying with a loud voice, came out of the man. 27They were all amazed, and they kept on asking one another, “What is this? A new teaching—with authority! He commands even the unclean spirits, and they obey him.” 28At once his fame began to spread throughout the surrounding region of Galilee.
