Humility. On his desk, Dr. Bob had a plaque defining humility:
"Perpetual quietness of heart.
It is to have no trouble. It is never to be fretted or vexed, irritable or sore; to wonder at nothing that is done to me, to feel nothing done against me.
It is to be at rest when nobody praises me, and when I am blamed or despised, it is to have a blessed home in myself where I can go in and shut the door and kneel to my Father in secret and be at peace, as in a deep sea of calmness, when all around and about is seeming trouble."
