When I pray for revival I pray first for the most radical thing: The utter devotion and allegiance of your hearts to Christ. That you would love Him so deeply and long for Him so passionately that His coming would be your great hope, and death would be gain, and life would be for Christ and His kingdom.
John PiperThe 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 Piper
