We 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. He beckons us into the obedience of suffering not to demonstrate the strength of our devotion to duty, nor to reveal the vigor of our moral resolve, nor to prove the heights of our tolerance for pain; but rather to manifest, in childlike faith, the infinite preciousness of his all-satisfying promises. Moses 'chose to share ill-treatment with the people of God rather than enjoy the fleeting pleasures of sin…because he looked to the reward' (Hebrews 11:25-26). Therefore his obedience glorified the reward of grace, not the resolve to suffer.
John Piper
