When you are downcast, or tempted, or angry, or frightened, ask yourself, “Have I made something else ‘my life’? That is, have I put something in the center of my life that doesn’t belong there?” To “set your heart on things above,” look at the thing and say, “You are not my life. Only Christ is my life. You’re a good thing but I don’t need you to have life and joy. Christ is my life and joy.”
