But the righteousness [1] which is by faith, etc. This passage is such as may not a little disturb the reader, and for two reasons -- for it seems to be improperly applied by Paul -- and the words are also turned to a different meaning. Of the words we shall hereafter see what may be said: we shall first notice the application. It is a passage taken from Deuteronomy 30:12, where, as in the former passage, Moses speaks of the doctrine of the law, and Paul applies it to evangelic promises. This knot may be thus untied: -- Moses shows, that the way to life was made plain: for the will of God was not now hid from the Jews, nor set far off from them, but placed before their eyes. If he had spoken of the law only, his reasoning would have been frivolous, since the law of God being set before their eyes, it was not easier to do it, than if it was afar off. He then means not the law only, but generally the whole of God's truth, which includes in it the gospel: for the word of the law by itself is never in our heart, no, not the least syllable of it, until it is implanted in us by the faith of the gospel. And then, even after regeneration, the word of the law cannot properly be said to be in our heart; for it demands perfection, from which even the faithful are far distant: but the word of the gospel has a seat in the heart, though it does not fill the heart; for it offers pardon for imperfection and defect. And Moses throughout that chapter, as also in the fourth, endeavors to commend to the people the remarkable kindness of God, because he had taken them under his own tuition and government, which commendation could not have belonged to the law only. It is no objection that Moses there speaks of forming the life according to the rule of the law; for the spirit of regeneration is connected with the gratuitous righteousness of faith. Nor is there a doubt but that this verse depends on that main truth, "the Lord shall circumcise thine heart," which he had recorded shortly before in the same chapter. They may therefore be easily disproved, who say that Moses speaks only in that passage of good works. That he speaks of works I indeed allow; but I deny it to be unreasonable, that the keeping of the law should be traced from its own fountain, even from the righteousness of faith. The explanation of the words must now follow. [2] Say not in thine heart, Who shall ascend? etc. Moses mentions heaven and the sea, as places remote and difficult of access to men. But Paul, as though there was some spiritual mystery concealed under these words, applies them to the death and resurrection of Christ. If any one thinks that this interpretation is too strained and too refined, let him understand that it was not the object of the Apostle strictly to explain this passage, but to apply it to the explanation of his present subject. He does not, therefore, repeat verbally what Moses has said, but makes alterations, by which he accommodates more suitably to his own purpose the testimony of Moses. He spoke of inaccessible places; Paul refers to those, which are indeed hid from the sight of us all, and may yet be seen by our faith. If then you take these things as spoken for illustration, or by way of improvement, you cannot say that Paul has violently or inaptly changed the words of Moses; but you will, on the contrary, allow, that without loss of meaning, he has, in a striking manner, alluded to the words heaven and the sea. Let us now then simply explain the words of Paul: As the assurance of our salvation lies on two foundations, that is, when we understand, that life has been obtained for us, and death has been conquered for us, he teaches us that faith through the word of the gospel is sustained by both these; for Christ, by dying, destroyed death, and by rising again he obtained life in his own power. The benefit of Christ's death and resurrection is now communicated to us by the gospel: there is then no reason for us to seek anything farther. That it may thus appear, that the righteousness of faith is abundantly sufficient for salvation, he teaches us, that included in it are these two things, which are alone necessary for salvation. The import then of the words, Who shall ascend into heaven? is the same, as though you should say, "Who knows whether the inheritance of eternal and celestial life remains for us?" And the words, Who shall descend into the deep? mean the same, as though you should say, "Who knows whether the everlasting destruction of the soul follows the death of the body?" He teaches us, that doubt on those two points is removed by the righteousness of faith; for the one would draw down Christ from heaven, and the other would bring him up again from death. Christ's ascension into heaven ought indeed fully to confirm our faith as to eternal life; for he in a manner removes Christ himself from the possession of heaven, who doubts whether the inheritance of heaven is prepared for the faithful, in whose name, and on whose account he has entered thither. Since in like manner he underwent the horrors of hell to deliver us from them, to doubt whether the faithful are still exposed to this misery, is to render void, and, as it were, to deny his death.

Footnotes

1 - Righteousness is here personified, according to the usual manner of the Apostle: law and sin had before been represented in the same way. -- Ed.

2 - It seems not necessary to have recourse to the distinctions made in the foregoing section. The character of the quotation given is correctly described in the words of Chrysostom, as quoted by Poole, "Paulus ea transtulit et aptavit ad jusitiam fidei -- Paul transferred and accommodated these things to the righteousness of faith." He evidently borrowed the words of Moses, not literally, but substantially, for the purpose of setting forth the truth he was handling. The speaker is not Moses, but "the righteousness of faith," represented as a person. Luther, as quoted by Wolfius, says, that "Paul, under the influence of the Spirit, took from Moses the occasion to form, as it were, a new and a suitable text against the justiciaries." It appears to be an application, by way of analogy, of the words of Moses to the gospel; but Pareus, Wolfius, Turrettin, and Doddridge, consider the words as applied by way of accommodation. -- Ed.

But the righteousness which is of faith - It is observable here that Paul does not affirm that Moses describes any where the righteousness by faith, or the effect of the scheme of justification by faith. His object was different, to give the Law, and state its demands and rewards. Yet though he had not formally described the plan of justification by faith, yet he had used language which would fitly express that plan. The scheme of justification by faith is here personified, as if it were living and describing its own effects and nature. One describing it would say, Or the plan itself speaks in this manner. The words here quoted are taken from Deuteronomy 30:11-14. The original meaning of the passage is this: Moses, near the end of his life, having given his commandments to the Israelites exhorts them to obedience. To do this, he assures them that his commands are reasonable, plain, intelligible, and accessible.
They did not require deep research, long journeys, or painful toil. There was no need of crossing seas, and going to other lands, of looking into the profound mysteries of the high heavens, or the deep abyss; but they were near them, had been plainly set before them, and were easily understood. To see the excellency of this characteristic of the divine Law, it may be observed, that among the ancients, it was not uncommon for legislators and philosophers to travel to distant countries in pursuit of knowledge. They left their country, encountered dangers on the sea and land, to go to distant regions that had the reputation of wisdom. Egypt was especially a land of such celebrity; and in subsequent times Pythagoras, and the principal philosophers of Greece, traveled into that country to converse with their priests, and to bear the fruits of their wisdom to benefit their native land. And it is not improbable that this had been done to some extent even in or before the time of Moses. Moses says that his precepts were to be obtained by no such painful and dangerous journeys. They were near them, plain, and intelligible. This is the general meaning of this passage Moses dwells on the thought, and places it in a variety of forms by the questions, "who shall go up to heaven for us, etc.;" and Paul regards this as appropriately describing the language of Christian faith; but without affirming that Moses himself had any reference in the passage to the faith of the gospel.
On this wise - In this manner.
Say not in thine heart - The expression to say in the heart is the same as to think. Do not think, or suppose, that the doctrine is so difficult to be understood, that one must ascend to heaven in order to understand it.
Who shall ascend into heaven? - This expression was used among the Jews to denote any difficult undertaking. To say that it was high as heaven, or that it was necessary to ascend to heaven to understand it, was to express the highest difficulty. Thus, Job 11:7, "Canst thou by searching find out God? It is high as heaven, what canst thou do? etc." Moses says it was not so with his doctrine. It was not impossible to be understood, but was plain and intelligible.
That is, to bring Christ - Paul does not here affirm that it was the original design of Moses to affirm this of Christ. His words related to his own doctrine. Paul makes this use of the words because,
(1) They appropriately expressed the language of faith.
(2) if this might be affirmed of the doctrines of Moses, much more might it of the Christian religion. Religion had no such difficult work to do as to ascend to heaven to bring down a Messiah. That work was already accomplished when God gave his Son to become a man, and to die.
To save man it was indeed indispensable that Christ should have come down from heaven. But the language of faith was that this had already been done. Probably the word "Christ" here includes all the benefits mentioned in Romans 10:4 as resulting from the work of Christ.

But the righteousness which is of faith - As it is most evident that there can be no justification by works, as all are sinful and all in a guilty state; if God will grant salvation at all, it must be by faith: but faith must have an object and a reason for its exercise; the object is Jesus Christ - the reason is the infinite merit of his passion and death.
Who shall ascend unto heaven? etc. - As Christ is the end of the law for justification to every one that believes, no observance of the law can procure him. Who, by the practice of the law, can bring Christ down from heaven? or, when brought down, and crucified and buried, as a sacrifice for sin, who can bring him up again from the dead? And both his death and resurrection are essentially necessary for the salvation of a lost world. Or the sense of the apostle may be this: They who will not believe in Christ crucified must in effect be seeking another Messiah to come down from heaven with a different revelation; or they who will not credit the doctrine that we preach concerning his resurrection seem in effect to say, Christ yet remains to be raised from the dead, and reign over the Jews as a mighty secular sovereign, subjecting the Gentile world to the sway of his righteous scepter.

But the righteousness which is of faith speaketh on this wise, (e) Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down [from above]:)
(e) Do not think to yourself, as men that are doubting do.

But the righteousness which is of faith,.... Or "with respect to the righteousness of faith"; the other righteousness before called the righteousness of God, because God is the author of it, here the righteousness of faith, because that receives it,
speaketh on this wise; the selfsame writer who describes the righteousness of the law in such a manner, that it gives no room to a fallen creature ever to expect life and salvation by it, gives such an account of the righteousness of faith, as forbids all doubting and despair:
say not in thine heart; let not such a thought enter into thy mind, much less express it with thy lips;
who shall ascend into heaven (that is, to bring Christ down from above, or who shall descend into the deep? that is, to bring up Christ again from the dead). These words are not properly a citation of Deuteronomy 30:12; but the apostle makes use of some phrases which are there, with his own explications of them; though the difference between them, stripped, of these explications is not very material: in the first clause, "who shall ascend into heaven?" the apostle leaves out the phrase, "for us"; which as to the sense was not absolutely necessary to retain; the difficulty, indeed, seems greater in the latter clause, "who shall descend into the deep?" which in the text of Moses is, "who shall go over the sea for us?" but when it is considered that the sea is often called the deep, and that sailing on it and over it, is expressed by "going down to the sea in ships", Psalm 107:23; and moreover, when it is observed that the Jerusalem Targum paraphrases it thus,
"the law is not in heaven that it should be said, oh that we had one of us, as Moses the prophet, who could go up to heaven and bring it to us! nor is it beyond the great sea, that it should be said, oh that we had one of us, as Jonah the prophet , "who could descend into the depths of the great sea", and bring it to us;''
the apostle is to be justified in his expressions. His sense, indeed, may seem to be different from that of Moses, and of the common interpretations of the Jewish writers, as in the above paraphrase and in the following account of them from the Talmud, understanding them of the law (w);
"says Abdimo bar Chama bar Dousa, what is the meaning of that Scripture, "neither is it in heaven, nor is it beyond the sea?" it is not in heaven, for if it was in heaven you must needs go up after it, and if it was beyond the sea, you must needs go over after it; Rabba says, not in heaven is it, you will not find it in him that exalts his knowledge in himself as the heavens, nor will you find it in him that enlarges his knowledge in himself, as the sea; R. Jochanan says, not in heaven is it, you will not find it in those that are of a haughty spirit, nor beyond the sea is it, you will not find it among traders abroad, or merchants.''
Though the apostle's sense may be brought pretty near to this, after this manner; who shall go up to heaven, or down to the deep, either to bring us the knowledge of the law, and yield an obedience to it which that requires of us, or to give us a full account of the Gospel of the grace of God? there is no room, nor reason, for men to say this in their hearts, or to make a doubt of them, as if they were not done already; to do so, is to deny that Christ is come in the flesh, and risen from the dead, who has given the true sense and knowledge of the law, and has perfectly fulfilled it, in the room and stead of his people, and by whom the doctrine of grace and truth is come, particularly the doctrine of a sinner's justification before God; this is brought nigh in the ministration of the word, so that there is no need of such inquiries as these. Moreover, for the illustration of these words, let it be observed, that these phrases are proverbial, and often used to express things impossible, of which take the following instances;
"it is a tradition of the Rabbins (x) if a man says to his wife, lo, this is thy divorce, on condition that "thou ascendest to the firmament", on condition that "thou descendest into the deep"; on condition that thou passest over the great sea on foot, this is no divorce;''
the reason is, , "because it is impossible". Again (y),
"if a man says to a woman, if thou wilt "ascend into the firmament", or if thou wilt "descend into the deep", lo, thou art espoused to me by this penny; but if thou wilt not go up into the firmament, nor go down into the deep, thou shalt not be espoused; and after that he puts the penny into her hand, lo, the condition becomes void, and behold she is espoused immediately, for the thing is known , "that it is impossible" for her to fulfil the condition.''
So here are forbidden all such thoughts, words, or expressions which carry such a sense as this; who will go down to the deep to fetch such a wretch as I am out of the lowest hell, to deliver me from the curses of the law, and the wrath of God, and bring me out of this wretched miserable condition in which I am? or go up to heaven and carry me there, and put me in the possession of the undefiled inheritance? all this is as impossible to be done, as for a man to ascend to heaven, or go down into the deep: now though the righteousness of the law encourages such despondency and black despair, the righteousness of faith, or the doctrine of justification by faith in Christ's righteousness, forbids every thing of this kind; assuring the sinner, that Christ is come down from heaven in human nature, that he has fulfilled all the righteousness of the law by his obedience in life, and has bore the penalty of it in his sufferings and death, and is risen again for justification; so that such questions should not be put, nor such despairing thoughts encouraged: besides, to think and speak in this manner, is to set aside the whole scheme of the Gospel, and supposes the person to doubt whether Christ is come down from heaven; and therefore asks, who shall go up to bring him down? and that he is not risen from the dead; and therefore puts the question, who will go down to the deep to fetch him up? whereas he is already come, has obeyed, suffered, and died, and rose again, and is become the end of the law for righteousness to everyone that believes.

But the--justifying
righteousness which is of faith speaketh on this wise--"speaketh thus"--its language or import is to this effect (quoting in substance Deuteronomy 30:13-14).
Say not in thine heart, Who shall ascend into heaven? that is, to bring Christ down, &c.--that is, "Ye have not to sigh over the impossibility of attaining to justification; as if one should say, oh! if I could but get someone to mount up to heaven and fetch me down Christ, there might be some hope, but since that cannot be, mine is a desperate case."

But the righteousness which is by faith - The method of becoming righteous by believing. Speaketh a very different language, and may be considered as expressing itself thus: (to accommodate to our present subject the words which Moses spake, touching the plainness of his law:) Say not in thy heart, Who shall ascend into heaven, as if it were to bring Christ down: or, Who shall descend into the grave, as if it were to bring him again from the dead - Do not imagine that these things are to be done now, in order to procure thy pardon and salvation. Deuteronomy 30:14.
