There is something about deepest humility which makes us bold. For utter obedience is self-forgetful obedience. No longer do we hesitate and shuffle and apologize because, say we, we are weak, lowly creatures and the world is a pack of snarling wolves among whom we are sent as sheep by the Shepherd (Matt. 10:16). I must confess that, on human judgment, the world tasks we face are appalling – well-nigh hopeless. Only the inner vision of God, only the God-blindedness of unreservedly dedicated souls, only the utterly humble ones can bow and break the raging pride of a power-mad world.
