Pastor Bryan Chapell writes in his recent book Grace at Work:

My musician wife, Kathy, talks about a time that she was chang­ing a particularly yucky diaper of one of our children. She said to a friend standing beside her, "These hands have played Mozart." The friend replied, "Maybe these hands are diapering the next Mozart!"

Possible Preaching Angle:

Undeniably, what those hands were doing was nurturing an eternal soul. When we are working to fulfill responsibilities God gives us, no matter how difficult or onerous the task, the Bible helps us to avoid thinking, “I'm just not doing something very important.”
