Discovering God’ s peace, which exceeds all understanding, in prayer is essential to peacemaking. (Phil 4:7). The peace given in prayer draws us into God, quieting our anxieties, challenging our old values and deepening wells of new energy. It arouses in us a compassionate love for all humanity and gives us heart to persevere beyond frustration, suffering and defeat. We should never forget that peace is not merely something that we ourselves as creatures do and accomplish, but it is in the ultimate analysis, a gift and a grace from God.
~Paul VI, John Paul II
