"Heal the sick . . ."
Christ invites his disciples to follow him by taking up their cross in their turn. By following him they acquire a new outlook on illness and the sick. Jesus associates them with his own life of poverty and service. He makes them share in his ministry of compassion and healing: "So they went out and preached that men should repent. And they cast out many demons, and anointed with oil many that were sick and healed them."
