One day Abba Isaac went to a monastery. He saw a brother committing a sin and he condemned him. When he returned to the desert, an angel of the Lord came and stood in front of the door of his cell and said, 'I will not let you enter.' But he persisted saying,'What is the matter:' and the angel replied, 'God has sent me to ask you where you want to throw the guilty brother whom you have condemned.' Immediately he repented and said, 'I have sinned, forgive me.' Then the angel said, 'Get up, God has forgiven you. But from now on, be careful not to judge someone before God has done so.'-- The Sayings of the Desert Fathers
"For us let it be enough to know ourselves to be in the place where God wants us, and carry on our work, even though it be no more than the work of an ant, infinitesimally small, and with unforeseeable results."
-- Abbé Monchanin
