It is clear that the general does not spare the strong soldiers from labor and danger, but the notion of an army requires that he sometimes expose them both to great labors and great dangers, but after victory is achieved the strong are honored more; so also the head of household commits the great labors to the better hired hands, but on payday gives them a greater reward; wherefore neither does divine providence have it so that those who are more good are freed from the adversity and labor of the present life, but rather that in the end they are better rewarded.
Aquinas, Super Iob, chapter 7.
