97 You see, my sons, what has been the end of those who followed these things, how being dead they yet work. Let us study to gain the diligence of those the glory of whose virtues we admire, and what we praise in others, let us silently recognize in ourselves. Nothing effeminate, nothing feeble attains to praise. “The kingdom of heaven suffers violence, and the violent take it by force.” The fathers ate the lamb in haste. Faith hastens, devotion is quick, hope is active, it loves not objections of the mind, but to pass from fruitless ease to the fruits of toil. Why do you put off till tomorrow? You can gain today; and must guard against not attaining the one and losing the other. The loss even of one hour is no slight one, one hour is a portion of our whole life.
