“"For it is God that worketh in you both to will and to work." "If He does Himself work in us to will, how dost thou exhort us? for if He works Himself even the will, the words, which you speak to us, have no meaning, 'that ye have obeyed'; for we have not 'obeyed'; it is without meaning that thou sayest, 'with fear and trembling'; for the whole is of God." It was not for this that I said to you, "for it is He that worketh in you both to will and to work," but my object was to relieve your anxiety. If thou wilt, in that case He will "work in thee to will." Be not affrighted, thou art not worsted; both the hearty desire and the accomplishment are a gift from Him: for where we have the will, thenceforward He will increase our will. For instance, I desire to do some good work: He has wrought the good work itself, and by means of it He has wrought also the will. Or he says this in the excess of his piety, as when he declares that our well-doings are gifts of grace. As then, when he calls these gifts, he does not put us out of the pale of free will, but accords to us free will, so when he says, "to work in us to will," he does not deprive us of free will, but he shows that by actually doing right we greatly increase our heartiness in willing. For as doing comes of doing, so of not doing comes not doing. Hast thou given an alms? thou art the more incited to give. Hast thou refused to give? thou art become so much the more disinclined. Hast thou practiced temperance for one day? Thou hast an incitement for the next likewise. Hast thou indulged to excess? Thou hast increased the inclination to self-indulgence. "When a wicked man cometh into the depth of vice, then he despises." As, then, when a man cometh into the depth of iniquity, he turns a despiser; so when he cometh into the depth of goodness, he quickens his exertions. For as the one runs riot in despair, so the second, under a sense of the multitude of good things, exerts himself the more, fearing lest he should lose the whole. "For His good pleasure," he says, that is, "for love's sake," for the sake of pleasing Him; to the end that what is acceptable to Him may take place; that things may take place according to His will. Here he shows, and makes it a ground of confidence, that He is sure to work in us, for it is His will that we live as He desires we should, and if He desires it, He Himself both worketh in us to this end, and will certainly accomplish it; for it is His will that we live aright. Seest thou, how he does not deprive us of free will?”

Augustine of Hippo Patristic
A.D. 354–430
“We should not suppose, because he said, "For it is God that works in you both the willing and the doing," that he has taken away free will. For if that were so he would not have said above "Work out your own salvation with fear and trembling." For when he bids them work, it is agreed that they have free will. But they are to work with fear and trembling so that they will not, by attributing the good working to themselves, be elated by the good works as though they were their own.”

“It is not that the will or the deed is not ours, but without his aid we neither will nor do anything good.”
“It is certain that when we do a deed the deed is ours; but he is the one who makes us do the deed by giving us strength fully sufficient to carry out our will.”
“It is not in God's power that anyone should be forced against his will to do evil or good but that he should go to the bad, according to his own deserts, when God abandons him. For a person is not good if he does not will it, but the grace of God assists him even in willing. It is not without cause that it is written, "God is the one who works in you to will and do, of his own good will."”

“Above he commended the humility of Christ; here he commends his reward, which is exaltation and glory. Lk. 14:11 and 18:14: *everyone who exalts himself will be humbled, and he who humbles himself will be exalted.* Job 22:29: *he who has been humbled will be in glory.* Note the threefold exaltation of Christ: namely as to the glory of the one rising, there "wherefore," etc.; as to the making known of his divinity, there "and he gave," etc.; and as to the reverence of the whole creature, there "that in the name," etc. He says therefore *wherefore God also exalted him*, namely that he might rise from death. Likewise, from mortality to immortality. Rom. 6:9: *Christ rising from the dead now dies no more, death will no longer have dominion over him.* Ps. 117:16f: *the right hand of the Lord has exalted me, I shall not die, but live.* Likewise, he exalted him by establishing him at his right hand. Eph. 1:20f: *establishing him at his right hand in the heavens above every principality, and power, and virtue, and dominion, and every name*, etc. But it is true that others are exalted in glory and in immortality; but he more so, because *he gave him a name*, etc. Now a name is imposed to signify some thing, and a name is the higher, the higher the thing signified by it is; and therefore the name of divinity is the higher. Ps. 8:2: *O Lord our Lord, how admirable is your name*, etc. Therefore this name, that he might be called and be God, the Father gave to this one, namely to Christ, as to the true God. But Photinus says that this is set down here as the reward of Christ's humility, and says that he is not true God, but that a certain eminence of a creature, and a likeness of divinity, was given to him — which is not true, because it was said above: *when he was in the form of God*, etc. It must therefore be said that in Christ there is a twofold nature, and one supposit. For this one person is God and man; and therefore this can be expounded in two ways. In one way, that the Father gave him this name insofar as he is the Son of God, and this from eternity through eternal generation; which giving is nothing other than his eternal generation. Jn. 5:26: *as the Father has life in himself, so he has given to the Son also to have life in himself*, etc. In another way, concerning Christ as man: and thus the Father gave to that man a name, that he might be God — not through nature, since the nature of God is one thing and that of man another, but that he might be God through grace, not of adoption but of union, by which he was at once God and man. Rom. 1:4: *predestined the Son of God in power*, he namely who was made to him from the seed of David according to the flesh. And this is the exposition of Augustine according to the intention of the apostle. Likewise it is found in Acts 2:36: *let all the house know most certainly*, etc. But the first is that of Ambrose. But you ask, objecting as to both expositions, why, after he said *he humbled himself*, etc., there follows here *wherefore*, etc., since a reward does not precede merit. Therefore neither the eternal generation nor the incarnation is the reward of Christ's passion, since they precede it. But it must be said that in sacred Scripture something is said to happen when it becomes known. *He gave* therefore, that is, he made manifest to the world, that he had this name. For this was made manifest in the resurrection, since before, the divinity of Christ was not so known. And the following text agrees with this — as though he did not give what he did not have, but that all might venerate this. And a twofold veneration is set down: namely in the subjection of work, and in the confession of mouth, there *and every tongue*, etc. He says therefore *and he gave him a name that is above every name*, even according as he is man. Therefore he adds *that in the name of Jesus*, which is the name of the man, *every knee should bow*. Phil. 2:10 and Isa. 45:24: *to me every knee shall bow*, etc. But here Origen erred: for when he heard that every knee should bow, which is to show reverence, he took it as a future event that at some time every rational creature — whether Angels, or men, or Demons — would be subjected to Christ by the subjection of charity. But against this stands Matt. 25:41: *depart, you cursed, into eternal fire*, etc. But it must be said that there is a twofold subjection: one voluntary, the other involuntary. And it is a future event that all the holy Angels will be subjected to Christ voluntarily; and therefore he says: *every knee should bow*. And the sign is put for the thing signified. Ps. 96:7: *adore him, all you his Angels.* Likewise, blessed men, and saints and the just, will be subjected in this manner. Ps. 85:9: *all the nations, whatsoever you have made, shall come, and shall adore before you, O Lord, and shall glorify your name.* But Demons and the damned not so, but are subjected involuntarily. Jas. 2:19: *the Demons believe, and tremble*, etc. Then when he says *and every tongue should confess*, etc., the showing of reverence in the confession of mouth is set down. *Every tongue* — namely of the heavenly, the earthly, and those of the lower regions. This is not said of the confession of praise with respect to those of the lower regions, but of a forced confession, which comes about through the recognition of God. Isa. 40:5: *all flesh together shall see, that the mouth of the Lord has spoken*, etc. Ps. 98:3: *let it confess to your great name, because it is terrible and holy*, etc. And this, *because the Lord Jesus Christ*, etc. — this one, namely the man — *in glory*, etc. He does not say "in a like glory," because in the same glory. Jn. 5:23: *let all honor the Son, as they honor the Father.* And it must be noted that at the beginning he says *who, when in the form*, etc., here he says *in glory*, because it was to be that what he had from eternity would become known to all, as in Jn. 17:5: *glorify me, you, Father, with yourself, with the glory which I had before the world was made, with you.* Then when he says *therefore, brethren*, etc., the exhortation is concluded. And concerning this he does three things: for first he exhorts to doing well; second he shows how they ought to act, there *but all things*, etc.; third, with what fruit, there *that you may be*, etc. Likewise the first divides into three: for first he recalls their past obedience; second he shows what they ought to do, there *not in presence*, etc.; third he gives confidence of fulfilling it, there *for God*, etc. He says therefore: therefore, since Christ so humbled himself and for this is exalted, you ought to know that if you humble yourselves you will also be exalted; and you ought to do this, because you have always obeyed. And he makes mention of obedience, commending their good deeds, and this for the reason that by obedience is understood every virtue — since it is from this that a man is just, that he keeps the commandments of God. Rom. 6:16: *you are the servants of him whom you obey, whether of sin unto death, or of obedience unto justice*, etc. Likewise, every good, however good it is in itself, is rendered better through obedience. Prov. 21:28: *an obedient man shall speak of victories.* Likewise, because obedience among the others is the greatest. For to offer of exterior things is great, but greater if of the body, but greatest if of the soul and your will — which is done through obedience. 1 Kgs. 15:22: *obedience is better than sacrifices, and to hearken rather than to offer the fat of rams*, etc. But if you have done thus, I exhort that you still do thus henceforth. Then when he says *not in presence*, etc., he shows what they ought to do. And first he admonishes them to act faithfully, because an unfaithful servant does not serve except when the master sees, since he cares for nothing but to please; but a faithful one always works well. And therefore he says *not in my presence only*, because otherwise it would seem that you were not acting from the instinct of good will. Eph. 6:6f: *not serving to the eye, as pleasing men, but as servants of Christ, doing the will of God: from the soul, with good will, serving the Lord, and not men.* Second, that they act humbly, there *with fear and trembling*, etc. For a proud man does not fear, but a humble one does. 1 Cor. 10:12: *he who thinks himself to stand, let him take heed lest he fall.* Prov. 28:14: *blessed is the man who is always fearful.* Ps. 2:11: *serve the Lord in fear, and rejoice unto him with trembling.* Third, that they act salutarily, there *work out your salvation.* Matt. 24:13: *he who shall persevere unto the end, he shall be saved.* Then when he says *for God*, etc., he confirms this confidence and excludes four false opinions. One, of men believing that man through free will can be saved without divine help. Against this he says *God*, etc. Jn. 14:10: *the Father abiding in me, he does the works*: and 15:5: *without me you can do nothing.* Others altogether deny free will, saying that man is necessitated by fate, or by divine providence. And this he excludes, when he says *in you*, because inwardly, through instinct, he moves the will to work well. Isa. 26:12: *for you have wrought all our works in us.* The third, of the Pelagians, as also the first, saying that the choosing is in us, but the carrying out of the works in God, since to will is from us but to accomplish is from God. And this he excludes, saying *both to will and to accomplish*. Rom. 9:16: *it is not of him that wills* — namely to will — *without the help of God, nor of him that runs* — namely to run — *but of God that shows mercy.* The fourth, that God does every good in us, and this through our merits. This he excludes, when he says *for good will* — namely his own, not for our merits — since before the grace of God there is no good merit in us. Ps. 50:20: *deal kindly, O Lord, in your good will*, etc.”

“For it is God which worketh in you,.... Which is both an encouragement to persons conscious of their own weakness to work, as before exhorted to; see Hag 2:4; and a reason and argument for humility and meekness, and against pride and vain glory, since all we have, and do, is from God; and also points out the spring, principle, and foundation of all good works; namely, the grace of God wrought in the heart, which is an internal work, and purely the work of God: by this men become the workmanship of God, created unto good works, Eph 2:10, and are new men, and fitted for the performance of acts of righteousness, and true holiness; and this grace, which God works in them, is wrought in a powerful and efficacious manner, so as not to be frustrated and made void. The word here used signifies an inward, powerful, and efficacious operation; and the "king's manuscript", mentioned by Grotius and Hammond, adds another word to it, which makes the sense still stronger, reading it thus, "which worketh in you", "by power"; not by moral persuasion, but by his own power, the power of his efficacious grace. The Alexandrian copy reads, "powers", or "mighty works": God works in his people both to will and to do of his good pleasure; God works in converted men a will to that which is spiritually good; which is to be understood, not of the formation of the natural faculty of the will; or of the preservation of it, and its natural liberty; or of the general motion of it to natural objects; nor of his influence on it in a providential way; but of the making of it good, and causing a willingness in it to that which is spiritually good. Men have no will naturally to come to Christ, or to have him to reign over them; they have no desire, nor hungerings and thirstings after his righteousness and salvation; wherever there are any such inclinations and desires, they are wrought in men by God; who works upon the stubborn and inflexible will, and, without any force to it, makes the soul willing to be saved by Christ, and submit to his righteousness, and do his will; he sweetly and powerfully draws it with the cords of love to himself, and to his Son, and so influences it by his grace and spirit, and which he continues, that it freely wills everything spiritually good, and for the glory of God: and he works in them also to "do"; for there is sometimes in believers a will, when there wants a power of doing. God therefore both implants in them principles of action to work from, as faith and love, and a regard for his glory, and gives them grace and strength to work with, without which they can do nothing, but having these, can do all things: and all this is "of his good pleasure"; the word "his" not being in the original text, some have taken the liberty to ascribe this to the will of man; and so the Syriac version renders it, "both to will and to do that", , "which ye will", or according to your good will; but such a sense is both bad and senseless; for if they have a good will of themselves, what occasion is there for God to work one in them? no; these internal operations of divine power and grace are not owing to the will of men, nor to any merits of theirs, or are what God is obliged to do, but what flow from his sovereign will and pleasure; who works when, where, and as he pleases, and that for his own glory; and who continues to do so in the hearts of his people; otherwise, notwithstanding the work of grace in them, they would find very little inclination to, and few and faint desires after spiritual things; and less strength to do what is spiritually good; but God of his good pleasure goes on working what is well pleasing in his sight.”

“For it is God which worketh in you - Every holy purpose, pious resolution, good word, and good work, must come from him; ye must be workers together with him, that ye receive not his grace in vain; because he worketh in you, therefore work with him, and work out your own salvation. To will and to do - Το θελειν και το ενεργειν. The power to will and the power to act must necessarily come from God, who is the author both of the soul and body, and of all their powers and energies, but the act of volition and the act of working come from the man. God gives power to will, man wills through that power; God gives power to act, and man acts through that power. Without the power to will, man can will nothing; without the power to work, man can do nothing. God neither wills for man, nor works in man's stead, but he furnishes him with power to do both; he is therefore accountable to God for these powers. Because God works in them the power to will and the power to do, therefore the apostle exhorts them to work out their own salvation; most manifestly showing that the use of the powers of volition and action belongs to themselves. They cannot do God's work, they cannot produce in themselves a power to will and to do; and God will not do their work, he will not work out their salvation with fear and trembling. Though men have grievously puzzled themselves with questions relative to the will and power of the human being; yet no case can be plainer than that which the apostle lays down here: the power to will and do comes from God; the use of that power belongs to man. He that has not got this power can neither will nor work; he that has this power can do both. But it does not necessarily follow that he who has these powers will use them; the possession of the powers does not necessarily imply the use of those powers, because a man might have them, and not use or abuse them; therefore the apostle exhorts: Work out your own salvation. This is a general exhortation; it may be applied to all men, for to all it is applicable, there not being a rational being on the face of the earth, who has not from God both power to will and act in the things which concern his salvation. Hence the accountableness of man. Of his good pleasure - Every good is freely given of God; no man deserves any thing from him; and as it pleaseth him, so he deals out to men those measures of mental and corporeal energy which he sees to be necessary; giving to some more, to others less, but to all what is sufficient for their salvation.”

“It is God who worketh in you both to will and to accomplish. We can neither have a will, nor begin, nor fulfil any thing of ourselves, in order to a reward in heaven. (Witham) — Our free-will is not taken away, or we should not be commanded to work; but it is added, with fear and trembling, says St. Augustine, that we might not be proud of our good works.

“We can rely on no purpose or effort of our own, but on Divine grace, for which we should earnestly pray. God moves us by His grace to will good, and He gives us strength to accomplish it : but our co-operation is necessary. St. Augustin remarks: "Not because the apostle saith, it is God that worketh in you both to will and work, must we think he taketh away our free will. For if it were so, then would he not a little before have willed them to work their own salvation with fear and trembling. For when they are commanded to work, their free will is called upon : but with trembling and fear is added, lest by attributing their well-working to themselves, they might be proud of their good deeds, as though they were of themselves." De gratia et lib. arb. c. ix. The good will iuS'oK.ia. may be the Divine good pleasure, by which God determines to bestow grace on the special objects of His favour; or the good disposition of the human will, under the influence of grace. No natural disposition, however excel- lent, can determine the Divine counsels in the distribution of grace. St. Chry- sostom explains it: "on account of His love, His pleasure, that the things pleasing to Him may be performed, that they may be according to His will."”

“For--encouragement to work: "For it is God who worketh in you," always present with you, though I be absent. It is not said, "Work out your own salvation, though it is God," &c., but, "because it is God who," &c. The will, and the power to work, being first instalments of His grace, encourage us to make full proof of, and carry out to the end, the "salvation" which He has first "worked," and is still "working in" us, enabling us to "work it out." "Our will does nothing thereunto without grace; but grace is inactive without our will" [ST. BERNARD]. Man is, in different senses, entirely active, and entirely passive: God producing all, and we acting all. What He produced is our own acts. It is not that God does some, and we the rest. God does all, and we do all. God is the only proper author, we the only proper actors. Thus the same things in Scripture are represented as from God, and from us. God makes a new heart, and we are commanded to make us a new heart; not merely because we must use the means in order to the effect, but the effect itself is our act and our duty (Eze 11:19; Eze 18:31; Eze 36:26) [EDWARDS]. worketh--rather as Greek, "worketh effectually." We cannot of ourselves embrace the Gospel of grace: "the will" (Psa 110:3; Co2 3:5) comes solely of God's gift to whom He will (Joh 6:44, Joh 6:65); so also the power "to do" (rather, "to work effectually," as the Greek is the same as that for "worketh in"), that is, effectual perseverance to the end, is wholly of God's gift (Phi 1:6; Heb 13:21). of his good pleasure--rather as Greek, "FOR His good pleasure"; in order to carry out His sovereign gracious purpose towards you (Eph 1:5, Eph 1:9).”
