All the different ways God has chosen to display his glory in creation and redemption seem to reach their culmination in the praises of his redeemed people. God governs the world with glory precisely that he might be admired, marvelled at, exalted and praised. The climax of his happiness is the delight he takes in the echoes of his excellence in the praises of the saints.
John PiperWe do not choose suffering simply because we are told to, but because the one who tells us to describes it as the path to everlasting joy.
John Piper
