9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
[Syncletica] also said, ‘When the devil does not use the goad of poverty to tempt us, he uses wealth for the same purpose. When he cannot win by scorn and mockery, he tries praise and flattery. If he cannot win by giving health, he tries illness. If he cannot win by comfort, he tries to ruin the soul by vexations that lead us to act against our monastic vows. He inflicts severe sicknesses on people whom he wants to tempt and so makes them weak, and thereby shakes the love they feel towards God. But although the body is shattered and running a high temperature and thirsting unbearably, yet you, who endure all this, are a sinner; you should therefore remember the punishments of the next world, the everlasting fire, the torments of judgement. Then you will not fail in the sufferings of this present time, indeed you should rejoice because God has visited you. Keep saying the famous text: “The Lord hath chastened and corrected me: but he hath not given me over unto death” (Ps. 118:18). Iron is cleaned of rust by fire. If you are righteous and suffer, you grow to a higher sanctity. Gold is tested by fire. When a messenger from Satan is given to you to be a thorn in your flesh, lift up your heart, for you have received a gift like that of St Paul. If you suffer from fever and cold, remember the text of Scripture, “We went through fire and water,” and “thou broughtest us out into a place of rest” (Ps. 66:12). If you have overcome suffering, you may expect rest, provided you are following what is good. Cry aloud the prophet’s words, “I am poor and destitute and in misery” (Ps. 66:29). Threefold suffering like this shall make you perfect. He said also, “Thou hast set me at liberty when I was in trouble” (Ps. 4:1). So let this kind of self-discipline test our souls, for our enemy is always in sight.’
Long-suffering therefore was God, when man became a defaulter, as foreseeing that victory which should be granted to him through the Word. For, when strength was made perfect in weakness,
Still, we must realize that as you cannot have a persecution without evil on the part of the devil or a trial of faith without a persecution, the evil that seems required for the trial of faith is not the cause of persecution but only its instrument. The real cause of the persecution is the act of God’s will, choosing that there be a trial of faith; then there follows evil on the part of the devil as the chosen instrument of persecution which is the proximate cause of the trial of faith. For in other respects too, insofar as evil is the rival of justice, to that extent it provides material to give testimony of that of which it is a rival, and so justice may be said to be perfected in injustice, as strength is perfected in weakness. For the weak things of the world are chosen by God that the strong may be put to shame, and the foolish things of this world to put to shame its wisdom. Thus even evil may be used that justice may be glorified when evil is put to shame.
All proof of abstinence is lost when excess is impossible; for sundry things have thus their evidence in their contraries. Just as "strength is made perfect in weakness," so likewise is continence made manifest by the permission to marry.
Is he then the same God as He who gave Satan power over the person of Job that his "strength might be made perfect in weakness? " How is it that the censurer of the Galatians still retains the very formula of the law: "In the mouth of two or three witnesses shall every word be established? " How again is it that he threatens sinners "that he will not spare" them -he, the preacher of a most gentle god? Yea, he even declares that "the Lord hath given to him the power of using sharpness in their presence!" Deny now, O heretic, (at your cost, ) that your god is an object to be feared, when his apostle was for making himself so formidable!
He will love the flesh which is, so very closely and in so many ways, His neighbour-(He will love it), although infirm, since His strength is made perfect in weakness; although disordered, since "they that are whole need not the physician, but they that are sick; " although not honourable, since "we bestow more abundant honour upon the less honourable members; " although ruined, since He says, "I am come to save that which was lost; " although sinful, since He says, "I desire rather the salvation of the sinner than his death; " although condemned, for says He, "I shall wound, and also heal.
In this way also "shall strength be made perfect in weakness," -saving what is lost, reviving what is dead, healing what is stricken, curing what is faint, redeeming what is lost, freeing what is enslaved, recalling what has strayed, raising what is fallen; and this from earth to heaven, where, as the apostle teaches the Philippians, "we have our citizenship, from whence also we look for our Saviour Jesus Christ, who shall change our body of humiliation, that it may be fashioned like unto His glorious body" -of course after the resurrection, because Christ Himself was not glorified before He suffered.
Lastly, when Paul is praying the Lord for its removal, what does he hear? "Hold my grace sufficient; for virtue is perfected in infirmity." This they who are surrendered to Satan cannot hear.
For in other respects, too, injustice in proportion to the enmity it displays against righteousness affords occasion for attestations of that to which it is opposed as an enemy, that so righteousness may be perfected in injustice, as strength is perfected in weakness. For the weak things of the world have been chosen by God to confound the strong, and the foolish things of the world to confound its wisdom.
When some infirmity and weakness and desolation attacks us, then our power is made perfect, and our faith is crowned if it has stood firm through temptation.
Paul is clearly teaching that the time for boasting is when one is being humiliated by unjust injuries. Christ gives us the power to endure these so that what previously appeared to be painful and loathsome may be accepted with gladness.
God told Paul that it was enough that he could raise the dead, cure the blind, cleanse lepers and do other miracles. He did not need exemption from danger and fear as well, or complete freedom to preach without any form of hindrance. Indeed, when these troubles come, God’s power of deliverance is shown, and the gospel triumphs in spite of persecution. The more the trials increased, the more grace increased as well.
"And He said to me, My grace is sufficient for you; for my power is made perfect in weakness."
That is to say, 'It is sufficient for you that you raise the dead, that you cure the blind, that you cleanse lepers, that you work those other miracles; seek not also exemption from danger and fear and to preach without annoyances. But are you pained and dejected lest it should seem to be owing to My weakness, that there are many who plot against and beat you and harass and scourge you? Why this very thing does show My power. "For My power," He says, "is made perfect in weakness," when being persecuted ye overcome your persecutors; when being harassed ye get the better of them that harass you; when being put in bonds ye convert them that put you in bonds. Seek not then more than is needed.' Do you see how he himself assigns one reason, and God another? For he himself says, "Lest I should be exalted overmuch, there was given to me a thorn;" but he says that God said He permitted it in order to show His power. 'You seek therefore a thing which is not only not needed, but which also obscures the glory of My power.' For by the words, "is sufficient for you," He would signify this, that nothing else need be added, but the whole was complete. So that from this also it is plain that he does not intend pains in the head; for in truth they did not preach when they were sick, for they could not preach when ill; but that harassed and persecuted, they overcame all. 'After having heard this then,' he says,
"Most gladly therefore will I glory in my weaknesses." For that they may not sink down, when those false Apostles are glorying over their contrary lot and these are suffering persecution, he shows that he shines all the brighter for this, and that thus the power of God shines forth the rather, and what happens is just matter for glorying. Wherefore he says, "Most gladly therefore will I glory." 'Not as therefore sorrowing did I speak of the things which I enumerated, or of that which I have just now said, "there was given to me a thorn;" but as priding myself upon them and drawing to myself greater power.' Wherefore also he adds,
"That the strength of Christ may rest upon me." Here he hints at another thing also, namely, that in proportion as the trials waxed in intensity, in the same proportion the grace was increased and continued.
The more one easily conquers, the less one needs combat. But who would fight within himself if there were no opposition from self? And why is there opposition from self if nothing remains in us to be healed and cured? Therefore, the sole cause of our fighting is weakness in ourselves. Again, weakness cautions against pride. Truly, that strength and virtue by which one is not proud in this life where he could be proud is made perfect in weakness.
