In this Gospel in the very beginning of Jesus’s ministry: John the Baptist is introduced; Jesus is baptized by John. Satan tempts Jesus. Jesus begins his Galilean ministry. He calls four fishermen: Peter, Andrew, James, and John. He expels an unclean spirit from a man. He heals Peter’s mother-in-law and many others and expels many demons. He goes on a preaching tour. He cleanses a leper with a command.
