And the Lord thy God will circumcise thine heart. This promise far surpasses all the others, and properly refers to the new Covenant, for thus it is interpreted by Jeremiah, who introduces God thus speaking, -- "Behold, the days come that I will make a new covenant with the house of Israel, and the house of Judah, not according to the covenant that I made with their fathers, which covenant they brake, but I will put my law in their inward parts, and write it in their hearts." (Jeremiah 31:31-33.) Moses now declares the same thing in different words, that, lest the Israelites, according to their wonted instability, should fall back from time to time into new rebellions, a divine remedy was needed, i.e., that God should renew and mould their hearts. In short, he reminds them that this would be the chief advantage of their reconciliation, that God should endow them with the Spirit of regeneration. There is a metaphor in this word circumcise; for Moses alludes to the legal sign of consecration, whereby they were initiated into the service of God. The expression, therefore, is equivalent to his saying, God will create you spiritually to be new men, so that, cleansed from the filth of the flesh and the world, and separated from the unclean nations, you should serve Him in purity. Meanwhile, he shews that, whatever God offers us in the Sacraments, depends on the secret operation of His Spirit. Circumcision was then the Sacrament of repentance and renewal, as Baptism is now to us; but "the letter," as Paul calls it, (Romans 2:27,) was useless in itself, as also now many are baptized to no profit. So far, then, is God from resigning the grace of His Spirit to the Sacraments, that all their efficacy and utility is lodged in the Spirit alone. Although Moses seems to make a division of the matter between men and God, so as to ascribe to them the beginning of repentance, and to make Him the author of perseverance (only, ) nevertheless this difficulty is easily solved; for according to the ordinary manner of Scripture, when he exhorts them to repentance, he is not teaching them that it is a gift of the Spirit, but simply reminding them of their duty. Meanwhile, the defenders of free-will foolishly conclude, that more is not required of men than they are able to perform; for in other places they are taught to ask of God whatever He enjoins. Thus, in this passage, Moses treats of the means of propitiating God, viz., by returning into the right way with an unfeigned heart; but, after he has testified that God will be gracious to them, he adds, that there is need of a better remedy, so that, being once restored by Him, they may be perpetual recipients of His grace. Still, it is not his intention to restrict the circumcision of the heart to the subsequent course of their lives, as if it depended on their own will and choice to circumcise themselves before God should work in them. And surely it is not at all more easy to rise when you have fallen, than to stand upright after God has set you up. I confess that perseverance is an excellent grace; but how shall the sinner, who is enthralled to Satan, free himself from those chains, unless God shall deliver him? Therefore, what Moses lays down as to the gift, of perseverance, applies no less to the commencement of conversion; but he only wishes to teach us that, although God should pardon our sins, that blessing would be but transient, unless He should keep us in subjection to His Law. And, in fact, He regenerates by His Spirit unto righteousness all those whose sins He pardons.
Circumcise thine heart - Compare Deuteronomy 10:16 note; Jeremiah 32:39; Ezra 11:19.
God will circumcise thine heart - This promise remains yet to be fulfilled. Their heart, as a people, has never yet been circumcised; nor have the various promises in this chapter been ever yet fulfilled. There remaineth, therefore, a rest for this people of God. Now, as the law, properly speaking, made no provision for the circumcision of the heart, which implies the remission of sins, and purification of the soul from all unrighteousness; and as circumcision itself was only a sign of spiritual good, consequently the promise here refers to the days of the Messiah, and to this all the prophets and all the apostles give witness: "for circumcision is that of the heart, in the spirit, and not in the letter," Romans 2:29; and the genuine followers of God are circumcised with the circumcision made without hands - by the circumcision of Christ," Colossians 2:11, Colossians 2:12. Hence we see these promises cannot be fulfilled to the Jews but in their embracing the Gospel of Christ. To look, therefore, for their restoration is idle and nugatory, while their obstinacy and unbelief remain.
And the LORD thy God will (e) circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
(e) God will purge all your wicked affections, a thing that is not in your own power to do.
And the Lord thy God will circumcise thine heart, and the heart of thy seed,.... No mention is made of circumcision of the flesh, which will now be out of use with the Jews; they being fully convinced of the abrogation of the ceremonial law by the Messiah, whom they will now receive. It is spiritual circumcision only that is here spoken of, with which the Jews will be circumcised, when they shall be pricked and cut to the heart, and be thoroughly convinced of sin; when the iniquity of their hearts will be laid open to them, and they put to pain, and filled with shame and loathing for it; when the hardness of their hearts will be removed, and the foolishness of them will be exposed and taken away, and they will be made willing to part with their sins, and with their own righteousness; when the graces of the Spirit will be implanted in them, and the blood of Christ applied to them for pardon and cleansing. This is the circumcision made without hands, which is not of men, but of God; what he calls for, and exhorts unto, as being necessary, Deuteronomy 10:16; he here promises to do; and deed none but himself can do it; for he only can come at the hearts of men, to take anything out of them, or put anything into them; it is he that opens the heart, softens, quickens, enlightens, and purifies it: Baal Hatturim says this respects the times of the Messiah:
to love the Lord thy God with all thine heart, and with all thy soul; which, though the duty of every man, is performed by none but those that have the grace of God; there is no love to God in the heart before this inward and spiritual circumcision of it: it is a fruit of the Spirit in conversion when the affections are taken off of other things, and set on Christ; when a man sees his sin and his Saviour, and the one is odious, and the other precious; when the blessings of grace are applied, and the love of God is shed abroad in the heart, which cause love to God and Christ again:
that thou mayest live; spiritually and eternally; for there is no spiritual life in the soul till the heart is circumcised, or, in other words, regenerated and renewed; then it is quickened; then a man lives a life of faith on Christ, of holiness from him, communion with him, and has both an open right unto, and meetness for, eternal life.
The Lord will then circumcise their heart, and the heart of their children (see Deuteronomy 10:16), so that they will love Him with all their heart. When Israel should turn with true humility to the Lord, He would be found of them, - would lead them to true repentance, and sanctify them through the power of His grace, - would take away the stony heart out of their flesh, and give them a heart of flesh, a new heart and a new spirit, - so that they should truly know Him and keep His commandments (vid., Ezekiel 11:19; Ezekiel 36:26; Jeremiah 31:33. and Deuteronomy 32:39.). "Because of thy life," i.e., that thou mayest live, sc., attain to true life. The fulfilment of this promise does not take place all at once. It commenced with small beginnings at the deliverance from the Babylonian exile, and in a still higher degree at the appearance of Christ in the case of all the Israelites who received Him as their Saviour. Since then it has been carried on through all ages in the conversion of individual children of Abraham to Christ; and it will be realized in the future in a still more glorious manner in the nation at large (Romans 11:25.). The words of Moses do not relate to any particular age, but comprehend all times. For Israel has never been hardened and rejected in all its members, although the mass of the nation lives under the curse even to the present day.
And the Lord - Or, For the Lord will circumcise thine heart, will by his word and spirit change and purge thy heart from all thine idolatry and wickedness, and incline thy heart to love him. God will first convert and sanctify them, the fruit whereof shall be, that they shall return and obey God's commandments, Deuteronomy 30:8, and then shall prosper in all things, Deuteronomy 30:9. This promise principally respects the times of the gospel, and the grace which was to be then imparted to all Israel by Christ.
