How the whole and the sick are to be admonished.
(Admonition 13.) Differently to be admonished are the whole and the sick. For the whole are to be admonished that they employ the health of the body to the health of the soul: lest, if they turn the grace of granted soundness to the use of iniquity, they be made worse by the gift, and afterwards merit the severer punishments, in that they fear not now to use amiss the more bountiful gifts of God. The whole are to be admonished that they despise not the opportunity of winning health for ever. For it is written, Behold now is the acceptable time, behold now is the day of salvation. They are to be admonished lest, if they will not please God when they may, they may be not able when, too late, they would. For hence it is that Wisdom afterward deserts those whom, too long refusing, she before called, saying, I have called, and you refused; I have stretched out my hand, and no man regarded; you have set at naught all my counsel, and would none of my reproof: I will also laugh at your destruction, and will mock when what you feared comes. And again, Then shall they call upon me, and I will not hearken; they shall rise early, and shall not find me. And so, when health of body, received for the purpose of doing good, is despised, it is felt, after it is lost, how precious was the gift: and at the last it is fruitlessly sought, having been enjoyed unprofitably when granted at the fit time. Whence it is well said through Solomon, Give not your honour unto aliens and your years unto the cruel, lest haply strangers be filled with your wealth, and your labours be in the house of a stranger, and you moan at the last, when your flesh and your body are consumed. For who are aliens from us but malignant spirits, who are separated from the lot of the heavenly country? And what is our honour but that, though made in bodies of clay, we are yet created after the image and likeness of our Maker? Or who else is cruel but that apostate angel, who has both smitten himself with the pain of death through pride, and has not spared, though lost, to bring death upon the human race? He therefore gives his honour unto aliens who, being made after the image and likeness of God, devotes the seasons of his life to the pleasures of malignant spirits. He also surrenders his years to the cruel one who spends the space of life accorded him after the will of the ill-domineering adversary. And in the same place it is well added, Lest haply strangers be filled with your wealth, and labours be in the house of a stranger. For whosoever, through the healthy estate of body received by him, or the wisdom of mind granted to him, labours not in the practice of virtues but in the perpetration of vices, he by no means fills his own house, but the habitations of strangers, with his wealth: that is, he multiplies the deeds of unclean spirits, and indeed so acts, in his luxuriousness or his pride, as even to increase the number of the lost by the addition of himself. Further, it is well added, And you moan at the last, when your flesh and your body are consumed. For, for the most part, the health of the flesh which has been received is spent through vices: but, when it is suddenly withdrawn, when the flesh is worn with afflictions, when the soul is already urged to go forth, then lost health, long enjoyed for ill, is sought again as though for living well. And then men moan for that they would not serve God, when altogether unable to repair the losses of their negligence by serving Him. Whence it is said in another place, When He slew them, then they sought Him.
But, on the other hand, the sick are to be admonished that they feel themselves to be sons of God in that the scourge of discipline chastises them. For, unless He purposed to give them an inheritance after correction, He would not have a care to educate them by afflictions. For hence the Lord says to John by the angel, Whom I love I rebuke and chasten. Hence again it is written, My son despise not the discipline of the Lord, nor faint when you are rebuked of Him. For whom the Lord loves He chastens, and scourges every son whom He receives. Hence the Psalmist says, Many are the tribulations of the righteous, and out of all these has the Lord delivered them. Hence also the blessed Job, crying out in his sorrow, says, If l be righteous, I will not lift up my head, being saturated with affliction and misery. The sick are to be told that, if they believe the heavenly country to be their own, they must needs endure labours in this as in a strange land. For hence it was that the stones were hammered outside, that they might be laid without sound of hammer in the building of the temple of the Lord; because, that is, we are now hammered with scourges without, that we may be afterwards set in our places within, without stroke of discipline, in the temple of God; to the end that strokes may now cut away whatever is superfluous in us, and then the concord of charity alone bind us together in the building. The sick are to be admonished to consider what severe scourges of discipline chastise our sons after the flesh for attaining earthly inheritances. What pain, then, of divine correction is hard upon us, by which both a never-to-be-lost inheritance is attained, and punishments which shall endure for ever are avoided? For hence Paul says, We have had fathers of our flesh as our educators, and we gave them reverence: shall we not much more be in subjection unto the Father of spirits and live? And they indeed for a few days educated us after their own will; but He for our profit in the receiving of His sanctification.
