The image is perfectly chosen: a door swings back and forth on its hinges but goes nowhere and accomplishes nothing. The sluggard's restless turning in bed is identical — motion without progress, activity without purpose. Laziness is not always stillness; sometimes it is purposeless movement.
Memory phrase: Move with a purpose.
Talk about it: What is the difference between moving and making progress?
Prayer: God, help me get up and do what is good.
