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 PiperThe only answer in these modern times, as in all other times, is the blood of Christ. When our conscience rises up and condemns us, where will we turn? We turn to Christ. We turn to the suffering and death of Christโthe blood of Christ. This is the only cleansing agent in the universe that can give the conscience relief in life and peace in death.
John PiperIt was becoming clearer and clearer that if I wanted to come to the end of my life and not say, โIโve wasted it!โ then I would need to press all the way in, and all the way up, to the ultimate purpose of God and join him in it. If my life was to have a single, all-satisfying, unifying passion, it would have to be Godโs passion.
John Piper
