23 “And my sorrow is continually before me.” What “sorrow” is that? Perhaps, a sorrow for my scourge. And, in good truth, my brethren, in good truth, let me say unto you, men do mourn for their scourges, not for the causes on account of which they are scourged. Not such was the person here. Listen, my brethren: If any person suffers any loss, he is more ready to say, “I did not deserve to suffer it,” than to consider why he suffered it, mourning the loss of money, not mourning over that of righteousness. If you have sinned, mourn for the loss of your inward treasure. You have nothing in your house, but perhaps you are still more empty in heart; but if your heart is full of its Good, even your God, why do you not say, “The Lord gave, the Lord has taken away; as it pleased the Lord was it done. Blessed be the Name of the Lord.” Whence then was it that He was grieving? Was it for the “scourging” wherewith He was scourged? God forbid. “And my sorrow” (says He) “is continually before me.” And as if we were to say, “What sorrow? Whence comes that sorrow?” he says: “For I declare mine iniquity; and I will have a care for my sin”. See here the reason for the sorrow! It is not a sorrow occasioned by the scourge; not one for the remedy, not for the wound. For the scourge is a remedy against sins. Hear, brethren; We are Christians, and yet if any one's son dies, he mourns for him but does not mourn for him if he sins. It is then, when he sees him sinning, that he ought to make mourning for him, to lament over him. It is then he should restrain him, and give him a rule to live by; should impose a discipline upon him: or if he has done so, and the other has not taken heed, then was the time when he ought to have been mourned over; then he was more fatally dead while living in luxury, than when, by death, he brought his luxury to its close: at that time, when he was doing such things in your house, he was not only “dead, but he stank also.” These things were worthy to be lamented, the others were such as might well be endured; those, I say, were tolerable, these worthy to be mourned over. They were to be mourned over in the same way that you have heard this person mourn over them: “For I declare mine iniquity. I will have a care for my sin.” Be not free from anxiety when you have confessed your sin, as if always able to confess your sin, and to commit it again. Do thou “declare your iniquity in such a manner, as to have a care for your sin.” What is meant by “having a care of your sin”? To have a care of your wound. If you were to say, “I will have a care of my wound,” what would be meant by it, but I will do my endeavour to have it healed. For this is “to have a care for one's sin,” to be ever struggling, ever endeavouring, ever exerting one's self, earnestly and zealously, to heal one's wound. Behold! You are from day to day mourning over your sins; but perhaps your tears indeed flow, but your hands are unemployed. Do alms, redeem your sins, let the poor rejoice of your bounty, that you also may rejoice of the Grace of God. He is in want; so are you in want also: he is in want at your hands; so are you also in want at God's hand. Do you despise one who needs your aid; and shall God not despise you when you need His? Do thou therefore supply the needs of him who is in want of your aid; that God may supply your needs within. This is the meaning of, “I will have a care for my sin.” I will do all that ought to be done, to blot out and to heal my sin. “And I will have a care for my sin.”
24. “But mine enemies live”. They are well off: they rejoice in worldly prosperity, while I am suffering, and “roaring with the groaning of my heart.” In what way do His enemies “live,” in that He has said of them already, that they have “spoken vanity”? Hear in another Psalm also: “Whose sons are as young plants; firmly rooted.” But above He had said, “Whose mouth speaks vanity. Their daughters polished after the similitude of a temple: their garners full bursting forth more and more; their cattle fat, their sheep fruitful, multiplying in their streets; no hedge falling into ruin; no cry in their streets.” “Mine enemies” then “live.” This is their life; this life they praise; this they set their hearts upon: this they hold fast to their own ruin. For what follows? They pronounce “the people that is in such a case” blessed. But what do you say, who “hast a care for your sin”? What do you say, who “confessest your iniquity”? He says, “Blessed is the people whose God is the Lord.”
“But mine enemies live, and are strengthened against me, and they that hate me wrongfully are multiplied.” What is “hate me wrongfully”? They hate me, who wish their good, whereas were they simply requiting evil for evil, they would not be righteous; were they not to requite with good the good done to them, they would be ungrateful: they, however, who “hate wrongfully,” actually return evil for good. Such were the Jews; Christ came unto them with good things; they requited Him evil for good. Beware, brethren, of this evil; it soon steals upon us. Let no one of you think himself to be far removed from the danger, because we said, “Such were the Jews.” Should a brother, wishing your good, rebuke you, and you hate him, you are like them. And observe, how easily, how soon it is produced; and avoid an evil so great, a sin so easily committed.
25. “They also that render evil for good, were speaking evil of me, because I have pursued the thing that is just”. Therefore was it that I was requited evil for good. What is meant by “pursued after the thing that is just”? Not forsaken it. That you might not always understand persecutio in a bad sense, He means by persecutus pursued after, thoroughly followed. “Because I have followed the thing that is just.” Hear also our Head crying with a lamentable voice in His Passion: “And they cast Me forth, Your Darling, even as a dead man in abomination.” Was it not enough that He was “dead”? Wherefore “in abomination” also? Because He was crucified. For this death of the Cross was a great abomination in their eyes, as they did not perceive that it was spoken in prophecy, “Cursed is every one that hangs on a tree.” For He did not Himself bring death; but He found it here, propagated from the curse of the first man; and this same death of ours, which had originated in sin, He had taken upon Himself, and hung on the Tree. Lest therefore some persons should think (as some of the Heretics think), that our Lord Jesus Christ had only a false body of flesh; and that the death by which He made satisfaction on the Cross was not a real death, the Prophet notices this, and says, “Cursed is every one that hangs on a tree.” He shows then that the Son of God died a true death, the death which was due to mortal flesh: lest if He were not “accursed,” you should think that He had not truly died. But since that death was not an illusion, but had descended from that original stock, which had been derived from the curse, when He said, “You shall surely die:” and since a true death assuredly extended even to Him, that a true life might extend itself to us, the curse of death also did extend to Him, that the blessing of life might extend even unto us. “And they cast Me forth, Your Darling, even as a dead man in abomination.”
