You get rewarded at the bottom end of the club by what you do at the top end. (Jerry Barber, late professional golfer)

Barber was talking about golf clubs and how important the grip is in determining the flight of the golf ball. It’s a great analogy, showing how important the relationship is between a tool and the craftsman who is using it. The golfer (or the machinist) has to put in the right effort at his end of the tool to be sure that the working end will do what he wants it to do.

Whatever you do, work at it with all your heart, as working for the Lord, not for human masters (Colossians 3:23).
