God's Just Judgments

When God’s judgments come upon a nation [Hurricanes] how do we account for the fact that there must be faithful believers in the midst of these judgments?

Saint Augustine, in the City of God, explains this with the following words;

Wherefore, though good and bad men suffer alike, we must not
suppose that there is no difference between the men themselves, because
there is no difference in what they both suffer. For even in the likeness of
the sufferings, there remains an unlikeness in the sufferers; and though
exposed to the same anguish, virtue and vice are not the same thing. For as
the same fire causes gold to glow brightly, and chaff to smoke; and under
the same flail the straw is beaten small, while the grain is cleansed; and as
the lees are not mixed with the oil, though squeezed out of the vat by the
same pressure, so the same violence of affliction proves, purges, clarifies
the good, but damns, ruins, exterminates the wicked. And thus it is that in
the same affliction the wicked detest God and blaspheme, while the good
pray and praise. So material a difference does it make, not what ills are
suffered, but what kind of man suffers them. For, stirred up with the same
movement, mud exhales a horrible stench, and ointment emits a fragrant
odor.
Augustine
