The suffering of sickness and the suffering of persecution have this in common: they are both intended by Satan for the destruction of our faith, and governed by God for the purifying of our faith... Christ sovereignly accomplishes His loving, purifying purpose, by overruling Satan's destructive attempts. Satan is always aiming to destroy our faith; but Christ magnifies His power in weakness.
John PiperSatan's aim is to destroy our joy and trust and delight in God, and to make God look worthless in the world's eyes. Everytime someone forsakes God for the world, gets angry at God when part of the world is taken away from them, they highlight the world as valuable... and everytime someone stays with God, when the world is taken away, and praises God, they highlight the value and glory of God.
John PiperGod created us to live with a single passion: to joyfully display his supreme excellence in all spheres of life. The wasted life is the life without this passion. God calls us to pray and think and dream and plan and work, not to be made much of, but to make much of him in every part of our lives.
John Piper
