Mark chapter 2 is about several important events in the life of Jesus. Jesus heals a paralyzed man: A paralyzed man is brought to Jesus, but there is no room for him to be brought into the house. So, people dig a hole in the roof and lower the man down to Jesus. Jesus tells the man that his sins are forgiven and then heals him, so he can walk.Jesus calls Levi: Jesus sees a tax collector named Levi sitting at his booth and calls him to follow him. Levi leaves his job to become a disciple of Jesus.Jesus eats with "sinners": Jesus eats with Levi and his friends, who were considered "sinners" by the religious leaders of the time. The religious leaders criticize Jesus for associating with such people.Jesus defends his disciples: The religious leaders criticize Jesus' disciples for picking grain on the Sabbath, but Jesus defends them by saying that the Sabbath was made for humans, not vice versa.Overall, Mark chapter 2 demonstrates Jesus' power to heal, his willingness to call unexpected people to follow him, and his challenging of religious traditions.
