Mark 1: 21-29 tells the story of Jesus teaching in the synagogue and being encountered by a man with unclean spirits. The first question we might as is what sort of legitimacy and authority do we give to NT texts about unclean spirits. The better question is whether Jesus still has the same power to heal and command. Mark is eager to impress on his readers that Jesus' authority was unlike any other. Where does Jesus claim to source his authority? How does Jesus use his authority? Pastor Caleb takes up these questions in this homily.
