“When you put your trust in Christ, the overpowering attraction of the world is broken. You are a corpse to the world, and the world is a corpse to you. Or to put it positively, you are a ‘new creation’ (Galatians 6:15). The old you is dead. A new you is alive — the you of faith in Christ. And what marks this faith is that it treasures Christ above everything in the world. The power of the world to woo your love away is dead.
Being dead to the world means that every legitimate pleasure in the world becomes a blood-bought evidence of Christ’s love and an occasion of boasting in the cross. When our hearts run back along the beam of blessing to the source in the cross, then the worldliness of the blessing is dead, and Christ crucified is everything.”John Piper
