In this installment of our studies on the Gospels, we look at the miraculous catch of fish that led to Peter, Andrew, James, and John forsaking all to follow Jesus Christ—but what exactly was the miracle and why did it have such a profound effect on Peter? Next, Jesus casts a demon out of a man at the synagogue in Capernaum. What does the Bible say about demons? The people there were astonished because Jesus taught with "authority"—a word that was loaded with meaning in first-century Jewish religious circles and carries deep meaning for Jesus' ministry—and for His followers today.
