You ought not, he says, to be troubled, for nothing strange, nothing contrary to expectation is happening; which was sufficient to raise them up. For do you see that on this account also Christ foretold to His disciples? For hear Him saying, “Now I have told you before it came to pass, that when it has come to pass ye may believe.” For greatly indeed, greatly does it tend to the comfort of others, to have heard from their teachers what is to happen. For as he that is sick, if he hear from his physician that this or that is taking place, is not much troubled; but if anything happen unexpectedly, as if he too were at a loss, and the disorder was beyond his art, he is afflicted and troubled; so also is it here. Which Paul foreknowing, foretold to them, “we are about to be afflicted,” “as it came to pass, and you know.” He not only says that this came to pass, but that he foretold many things, and they happened. “Hereunto we are appointed.” So that not only ye ought not to be troubled and disturbed about the past, but not even about the future, if any such thing should happen, “for hereunto we are appointed.”
Moral. Let us hear, who have ears to hear. The Christian is appointed hereunto. For concerning all the faithful is this said, “Hereunto we are appointed.” And we, as if we were appointed for ease, think it strange if we suffer anything; and yet what reason have we for thinking anything strange? For no season of affliction or temptation has overtaken us, but what is common to man. It is a fit season for us to say to you, “You have not yet resisted unto blood, striving against sin”. Or rather, this is not seasonable for us to say to you— but what? You have not yet despised riches. For to them indeed these words were said with reason, when they had lost all their own possessions, but this is said to those who retain theirs. Who has been robbed of his riches for Christ's sake? Who has been beaten? Who has been insulted? Even in words, I mean. What have you to boast of? What confidence have you to say anything? So many things Christ suffered for us when we were enemies. What can we show that we have suffered for Him? Nothing that we have suffered indeed, but infinite good things that we have received from Him. Whence shall we have confidence in that Day? Do you not know, that the soldier too, when he can show numberless wounds and scars, will then be able to shine in the presence of the king? But if he has no good action to show, though he may have done no harm, he will take rank among the least.
But, you say, it is not the season of war. But if it was, tell me, who would contend? Who would attack? Who would break through the phalanx? Perhaps no one. For when I see that you do not despise riches for the sake of Christ, how shall I believe that you will despise blows? Tell me, do you bear manfully those who insult you, and do you bless them? You do not— but you disobey. What is attended with no danger, you do not; and will you endure blows, in which there is much pain and suffering? Do you not know that it is proper in peace to keep up the exercises of war? Do you not see these soldiers, who though no war disturbs them, but it is profound peace, brightening up their arms, and going forth with the teachers who teach them tactics, into the broad and level plains, I may say, every day, keep up with the greatest strictness the exercises of war? Of our spiritual soldiers, who has done this? No one. For this reason we become in war weak and ignoble, and easily led captive by any.
But what stupidity is this, not to think the present a season of war, when Paul is crying out, “Yea, and all that would live godly in Christ Jesus shall suffer persecution”; and Christ says, “In the world you shall have tribulation.” And again the blessed Paul with a loud voice cries out, saying, “Our wrestling is not against flesh and blood,” and again, “Stand therefore, having girded your loins with truth.” Why do you arm us, tell me, when it is not war? Why do you give us trouble to no purpose? You put breastplates on the soldiers, when it is allowed them to rest and revive. But he would have said, Certainly, however, though it were not war, it would be right to attend to the concerns of war. For he who in peace considers the business of battle, will be formidable in the season of battle; but he who is without experience in the things of war, will be more troubled even in peace. Why so? Because he will weep for the things which he possesses, and not being able to fight for them, will be in anguish. For the possessions of the cowardly and inexperienced and ignoble in war, are the property of all who are brave and warlike. So that on this account first I arm you. But then also the whole time of our life is the season of war. How and in what respect? The devil is ever at hand. Hear what it says, “As a roaring lion, he walks about, seeking whom he may devour.” Numberless bodily affections assail us, which it is necessary to enumerate, that we may not vainly deceive ourselves. For tell me, what does not war against us? Riches, beauty, pleasure, power, authority, envy, glory, pride? For not only does our own glory war against us, forbidding us to descend to humility; but the glory of others also, leading us to envy and ill-nature. But what do their opposites, poverty, dishonor, the being despised, rejected, the having no power? These things indeed are in us. But from men proceed wickedness, plots, deceits, slanders, assaults innumerable. In like manner on the part of the demons, “principalities, powers, the world rulers of this darkness, spiritual hosts of wickedness.” Some of us are rejoicing, others grieving, both are deviations from the right course. But health and sickness (war against us). From what quarter will not man be falling into sin? Would you that I should tell you from the beginning, commencing even immediately from Adam? What took captive the first created? Pleasure, and eating, and the love of dominion. What the son who came next after him? Grudging and envy. What those in the time of Noah? Fleshly pleasures, and the evils issuing from them. What his son? Insolence and irreverence. What the Sodomites? Insolence, wantonness; and fullness of bread. But often even poverty has this effect. On this account a certain wise man said, “Give me neither poverty nor riches.” However it is neither poverty nor riches, but the will that cannot use either of them. “Acknowledge,” he says, “that you pass through the midst of snares.”
The blessed Paul has admirably said, “Hereunto we are appointed.” He has not said merely, that we are tempted, but that “hereunto we are appointed,” as if he had said, For this were we born. This is our business, this our life, and do you seek rest? The executioner does not stand over us, lacerating our sides, and compelling us to sacrifice; but the desire of riches, and of possessing more, is instant, tearing out our eyes. No soldier has kindled a pile, nor placed us on a gridiron, but more than this, the flames of the flesh set fire on our souls. No king is present promising numberless bounties, and putting us out of countenance. But there is present a rage for glory, tickling us worse than he. A great war, truly, exceedingly great, if we would watch.
