There is no holiness, Lord, if you withdraw you hand. No wisdom is of any use if you no longer guide it. No strength can avail if you do not preserve it. No purity is safe if you do not protect it. No watchfulness on our part can affect anything unless your holy vigilance is present with us. If you abandon us, we sink and perish; but if you come to us, we are raised up and we live.
– Thomas à Kempis
