Augustine of Hippo

But if this anomalous state of things were uniform in this life, in which, as the sacred Psalmist says, "Man is like to vanity, his days as a shadow that passeth away,"—so uniform that none but wicked men won the transitory prosperity of earth, while only the good suffered its ills,—this could be referred to the just and even benign judgment of God. We might suppose that they who were not destined to obtain those everlasting benefits which constitute human blessedness were either deluded by transitory blessings as the just reward of their wickedness, or were, in God's mercy, consoled them, and that they who were not destined to suffer eternal torments were afflicted with temporal chastisement for their sins, or were stimulated to greater attainment in virtue. But now, as it is, since we not only see good men involved in the ills of life, and bad men enjoying the good of it, which seems unjust, but also that evil often overtakes evil men, and good surprises the good, the rather on this account are God's judgments unsearchable, and His ways past finding out.
