From John Piper's Supremacy of Christ
All the planets of your life—your sexuality and desires, your commitments and beliefs, your aspirations and dreams, your attitudes and convictions, your habits and disciplines, your solitude and relationships, your labor and leisure, your thinking and feeling—all the planets of your life are held in orbit by the greatness and gravity and blazing brightness of the supremacy of Jesus Christ at the center of your life. And if he ceases to be the bright, blazing, satisfying beauty at the center of your life, the planets will fly into confusion, and a hundred things will be out of control, and sooner or later they will crash into destruction.
… Oh, that the almighty God would help us see and savor the supremacy of his Son. Give yourself to this. Study this. Cultivate this passion. Eat and drink and sleep this quest to know the supremacy of Christ.
