The Gospel and the first reading both remind us of the transience of this world. Through Isaiah, God reminded David that his enemies were merely men, heads of states that would not last forever, indeed for only sixty-five years (Is.7:8). Jesus links survival with faith and repentance, the faith to recognise Him through His miracles and repentance as the perfect response to that recognition. Jesus' words, in a different context and with a different thrust, affirm Isaiah's words: Unless your faith is firm, you shall not be firm."

States and cities, nations and peoples, rise and fall throughout history, but God still speaks to our hearts in every age and circumstance: "Take care you remain tranquil and do not fear." The word of God always bears fruit in the heart of the person who receives it in faith. Faith in God amid difficulties and suffering will bring us tranquillity and the courage not to be afraid. In the Gospels, we frequently hear Jesus assuring people that their faith has brought them healing. Healing often takes the form of peace and tranquillity, courage and patience, hope and trust.
