In this chapter the apostle deals plainly with those who hearkened to the judaizing teachers, who cried up the law of Moses in competition with the gospel of Christ, and endeavored to bring them under the bondage of it. To convince them of their folly, and to rectify their mistake herein, in these verses he prosecutes the comparison of a child under age, which he had touched upon in the foregoing chapter, and thence shows what great advantages we have now, under the gospel, above what they had under the law. And here.

I.He acquaints us with the state of the Old Testament church: it was like a child under age, and it was used accordingly, being kept in a state of darkness and bondage, in comparison of the greater light and liberty which we enjoy under the gospel. That was indeed a dispensation of grace, and yet it was comparatively a dispensation of darkness; for as the heir, in his minority, is under tutors and governors till the time appointed of his father, by whom he is educated and instructed in those things which at present he knows little of the meaning of, though afterwards they are likely to be of great use to him; so it was with the Old Testament church - the Mosaic economy, which they were under, was what they could not fully understand the meaning of; for, as the apostle says (Co2 3:13), They could not stedfastly look to the end of that which is abolished. But to the church, when grown up to maturity, in gospel days, it becomes of great use. And as that was a dispensation of darkness, so of bondage too; for they were in bondage under the elements of the world, being tied to a great number of burdensome rites and observances, by which, as by a kind of first rudiments, they were taught and instructed, and whereby they were kept in a state of subjection, like a child under tutors and governors. The church then lay more under the character of a servant, being obliged to do every thing according to the command of God, without being fully acquainted with the reason of it; but the service under the gospel appears to be more reasonable than that was. The time appointed of the Father having come, when the church was to arrive at its full age, the darkness and bondage under which it before lay are removed, and we are under a dispensation of greater light and liberty.

II.He acquaints us with the much happier state of Christians under the gospel-dispensation, Gal 4:4-7. When the fulness of time had come, the time appointed of the Father, when he would put an end to the legal dispensation, and set up another and a better in the room of it, he sent forth his Son, etc. The person who was employed to introduce this new dispensation was no other than the Son of God himself, the only-begotten of the Father, who, as he had been prophesied of and promised from the foundation of the world, so in due time he was manifested for this purpose. He, in pursuance of the great design he had undertaken, submitted to be made of a woman - there is his incarnation; and to be made under the law - there is his subjection. He who was truly God for our sakes became man; and he who was Lord of all consented to come into a state of subjection and to take upon him the form of a servant; and one great end of all this was to redeem those that were under the law - to save us from that intolerable yoke and to appoint gospel ordinances more rational and easy. He had indeed something more and greater in his view, in coming into the world, than merely to deliver us from the bondage of the ceremonial law; for he came in our nature, and consented to suffer and die for us, that hereby he might redeem us from the wrath of God, and from the curse of the moral law, which, as sinners, we all lay under. But that was one end of it, and a mercy reserved to be bestowed at the time of his manifestation; then the more servile state of the church was to come to a period, and a better to succeed in the place of it; for he was sent to redeem us, that we might receive the adoption of sons - that we might no longer be accounted and treated as servants, but as sons grown up to maturity, who are allowed greater freedoms, and admitted to larger privileges, than while they were under tutors and governors. This the course of the apostle's argument leads us to take notice of, as one thing intended by this expression, though no doubt it may also be understood as signifying that gracious adoption which the gospel so often speaks of as the privilege of those who believe in Christ. Israel was God's son, his first-born, Rom 9:4. But now, under the gospel, particular believers receive the adoption; and, as an earnest and evidence of it, they have together therewith the Spirit of adoption, putting them upon the duty of prayer, and enabling them in prayer to eye God as a Father (Gal 4:6): Because you are sons, God hath sent forth the Spirit of his Son into your hearts, crying Abba, Father. And hereupon (Gal 4:7) the apostle concludes this argument by adding, Wherefore thou art no more a servant, but a son; and, if a son, then an heir of God through Christ; that is, Now, under the gospel state, we are no longer under the servitude of the law, but, upon our believing in Christ, become the sons of God; we are thereupon accepted of him, and adopted by him; and, being the sons, we are also heirs of God, and are entitled to the heavenly inheritance (as he also reasons Rom 8:17), and therefore it must needs be the greatest weakness and folly to turn back to the law, and to seek justification by the works of it. From what the apostle says in these verses, we may observe,

1.The wonders of divine love and mercy towards us, particularly of God the Father, in sending his Son into the world to redeem and save us, - of the Son of God, in submitting so low, and suffering so much, for us, in pursuance of that design, - and of the Holy Spirit, in condescending to dwell in the hearts of believers for such gracious purposes.

2.The great and invaluable advantages which Christians enjoy under the gospel; for, (1.) We receive the adoption of sons. Whence note, It is the great privilege which believers have through Christ that they are adopted children of the God of heaven. We who by nature are children of wrath and disobedience have become by grace children of love. (2.) We receive the Spirit of adoption. Note, [1.] All who have the privilege of adoption have the Spirit of adoption - all who are received into the number partake of the nature of the children of God; for he will have all his children to resemble him. [2.] The Spirit of adoption is always the Spirit of prayer, and it is our duty in prayer to eye God as a Father. Christ has taught us in prayer to eye God as our Father in heaven. [3.] If we are his sons, then his heirs. It is not so among men, with whom the eldest son is heir; but all God's children are heirs. Those who have the nature of sons shall have the inheritance of sons.

Thou art no more a servant - Thou who hast believed in Christ art no longer a slave, either under the dominion of sin or under obligation to the Mosaic ritual; but a son of God, adopted into the heavenly family.

And if a son, then an heir - Having a right to the inheritance, because one of the family, for none can inherit but the children; but this heirship is the most extraordinary of all: it is not an heirship of any tangible possession, either in heaven or earth; it is not to possess a part or even the whole of either, it is to possess Him who made all things; not God's works, but God himself: heirs of God through Christ.

Wherefore thou art no more a servant,.... This is a benefit resulting from adoption, and the manifestation of it to the children of God, and supposes them to have been formerly servants; as whilst in a natural state they were the servants of sin, the vassals of Satan, slaves to the world, and the lusts of it, and in bondage to the law; but now being declared to be the sons of God under the witnessings of the Spirit, they are freed from the servitude of sin, from the captivity of Satan, from the slavery of the world, and particularly from the law, and that spirit of bondage which it brought upon them, which is chiefly designed; and from which they are delivered by the spirit of adoption, enabling and encouraging them to cry "Abba", Father; so that they are now no more under the former servile spirit, the spirit of a servant,

but a son; whose spirit, state, and case, are vastly different from those of a servant: the servant has not that interest in his master's affections as the son has; nor that liberty of access to him; nor is he fed and clothed as he is, or shares in the same privileges he does; nor is his obedience performed in the same free generous manner, from a principle of love and gratitude, but in a servile and mercenary way; and though he may expect his wages, he cannot hope for the inheritance; nor does he always abide in the house as the son does. He that is once a son, is always so, and no more a servant: predestination to sonship is immutable; it is God's act to put any among the children, and none can put them out; the covenant of grace, in which this blessing is secured, is unalterable; union with Christ, the Son of God, on which it is founded, is indissoluble; the spirit of adoption, wherever he witnesses, abides as such. They that are the sons of God may be corrected and chastised, as they often are, in a fatherly way; but these corrections are proofs for, and not against their sonship; they may indeed judge themselves unworthy to be called the sons of God, and may be in such frames of soul as to conclude, at least fear, they are not; but still the relation abides, and ever will. They will never more be servants, but always sons. The very learned Mr. Selden (i) thinks the apostle alludes to a custom among the Jews, who allowed only freemen, and not servants and handmaids, to call any Abba, Father such an one, or "Imma", Mother such an one: but this seems to proceed upon a mistaken sense, and rendering of a passage in the Talmud (k), which is as follows, ; which he thus renders, "neither servants nor handmaids use this kind of appellation, Abba", or "Father such an one", and "Imma", or "Mother such an one"; whereas it should be rendered, "servants and handmaids, they do not call them Abba, Father such an one", and "Imma, Mother such an one"; this is clear from what follows. "The Family of "R. Gamaliel" used to call them Father such an one, and Mother such an one"; which in the other Talmud (l) is, "the family of" R. Gamaliel "used to call their servants and their handmaids Father Tabi, and Mother Tabitha"; which were the names of the servant and handmaid of Gamaliel. Rather therefore reference is had to a tradition (m) of theirs, that

"a servant, who is carried captive, when others redeemed him, if under the notion of a servant, or in order to be one, he becomes a servant; but if under the notion of a freeman, , "he is no more a servant".''

Or to the general expectation of that people, that when they are redeemed by the Messiah, they shall be servants no more; for so they say (n),

"your fathers, though they were redeemed, became servants again, but you, when ye are redeemed, , "shall be no more servants";''

which in a spiritual sense is true of all that are redeemed by Christ, and through that redemption receive the adoption of children, and is what the apostle here means.

And if a son, then an heir of God through Christ; which is another benefit arising from adoption. Such as are the children of God, they are heirs of God himself; he is their portion and exceeding great reward; his perfections are on their side, and engaged for their good; all his purposes run the same way, and all his promises belong to them; they are heirs of all the blessings of grace and glory, of righteousness, of life, of salvation, and a kingdom and glory; and shall inherit all things, and all "through Christ": he is the grand heir of all things; they are joint heirs with him; their sonship is through him, and so is their heirship and inheritance; their inheritance is in his possession, it is reserved safe in him; and by him, and with him they shall enjoy it. The Alexandrian copy, and some others, only read, "an heir through God", and so the Vulgate Latin version; and the Ethiopic version only, "an heir of God".

Wherefore--Conclusion inferred from Gal 4:4-6.

thou--individualizing and applying the truth to each. Such an individual appropriation of this comforting truth God grants in answer to them who cry, "Abba, Father."

heir of God through Christ--The oldest manuscripts read, "an heir through God." This combines on behalf of man, the whole before-mentioned agency, of THE TRINITY: the Father sent His Son and the Spirit; the Son has freed us from the law; the Spirit has completed our sonship. Thus the redeemed are heirs THROUGH the Triune GOD, not through the law, nor through fleshly descent [WINDISCHMANN in ALFORD]; (Gal 3:18 confirms this).

heir--confirming Gal 3:29; compare Rom 8:17.
