From Jim Towey's November 8, 2008, Wall Street Journal op-ed:
Mother Teresa was asked at the end of her life whether she was discouraged because after decades of caring for the dying and destitute in Calcutta little seemed to have changed. She replied, “No. God doesn't call me to be successful. God calls me to be faithful.”
History will decide whether George W. Bush was a successful President. But he was faithful. He had a charge to keep and he kept it.
