In a video produced about his life, President Thomas S. Monson expressed his desire to be an instrument in the Lord's hands.
"The sweetest experience I know in life is to feel a prompting and act upon it and later find out that it was the fulfillment of someone’s prayer or someone’s need," he said. "And I always want the Lord to know that if He needs an errand run, Tom Monson will run that errand for Him."
