I remember reading an article about Mother Teresa where she was visiting "House of Dying" with Mark Hatfield. She was asked how she could bear the load (that is, caring and ministering for the poor and the sick children) without being crushed by it, she replied, "My dear Senator, I am not called to be successful, I am called to be faithful."
Like Mother Teresa, may we be faithful to God, to the people He sends our way and to the talents, time, blessings and opportunities He's given us - no matter what.
