Fulton J. Sheen said this quote

Conversion can also occur among those who already have the faith. Christians will become real Christians, with less façade and more foundation. Catastrophe will divide them from the world, force them to declare their basic loyalties; it will revive shepherds who shepherd rather than administrate, reverse the proportion of saints and scholars in favor of saints, create more reapers for the harvest, more pillars of fire for the lukewarm; it will make the rich see that real wealth is in the service of the needy; and, above all else, it will make the glory of Christ’s Cross shine out in a love of the brethren for one another as true and loyal sons of God.
