29 If you are Christ's, then you are Abraham's seed and heirs according to promise.
Neither, because they are Abraham's seed, are they all children. But, "In Isaac will your seed be called." That is, it is not the children of the flesh who are children of God, but the children of the promise are counted as a seed.
For it is written that Abraham had two sons, one by the handmaid, and one by the free woman. However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise. These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar. For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children. But the Jerusalem that is above is free, which is the mother of us all. For it is written, "Rejoice, you barren who don't bear. Break forth and shout, you that don't travail. For more are the children of the desolate than of her who has a husband." Now we, brothers, as Isaac was, are children of promise. But as then, he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. However what does the Scripture say? "Throw out the handmaid and her son, for the son of the handmaid will not inherit with the son of the free woman." So then, brothers, we are not children of a handmaid, but of the free woman.
Therefore she said to Abraham, "Cast out this handmaid and her son! For the son of this handmaid will not be heir with my son, even with Isaac." The thing was very grievous in Abraham's sight on account of his son. God said to Abraham, "Don't let it be grievous in your sight because of the boy, and because of your handmaid. In all that Sarah says to you, listen to her voice. For from Isaac will your seed be called.
whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come. All are yours, and you are Christ's, and Christ is God's.
For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the seed, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all. As it is written, "I have made you a father of many nations." This is in the presence of him whom he believed: God, who gives life to the dead, and calls the things that are not, as though they were. Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, "So will your seed be." Without being weakened in faith, he didn't consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah's womb. Yet, looking to the promise of God, he didn't waver through unbelief, but grew strong through faith, giving glory to God, and being fully assured that what he had promised, he was able also to perform.
The father of circumcision to those who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham, which he had in uncircumcision. For the promise to Abraham and to his seed that he should be heir of the world wasn't through the law, but through the righteousness of faith. For if those who are of the law are heirs, faith is made void, and the promise is made of no effect.

Commentary on Galatians 3 Matthew Henry Commentary
Chapter 3
The apostle in this chapter,
Gal 3:1-5
The apostle is here dealing with those who, having embraced the faith of Christ, still continued to seek for justification by the works of the law; that is, who depended upon their own obedience to the moral precepts as their righteousness before God, and, wherein that was defective, had recourse to the legal sacrifices and purifications to make it up. These he first sharply reproves, and then endeavours, by the evidence of truth, to convince them. This is the right method, when we reprove any for a fault or an error, to convince them that it is an error, that it is a fault.
He reproves them, and the reproof is very close and warm: he calls them foolish Galatians, v. 1. Though as Christians they were Wisdom's children, yet as corrupt Christians they were foolish children. Yea, he asks, Who hath bewitched you? whereby he represents them as enchanted by the arts and snares of their seducing teachers, and so far deluded as to act very unlike themselves. That wherein their folly and infatuation appeared was that they did not obey the truth; that is, they did not adhere to the gospel way of justification, wherein they had been taught, and which they had professed to embrace. Note, It is not enough to know the truth, and to say we believe it, but we must obey it too; we must heartily submit to it, and stedfastly abide by it. Note, also, Those are spiritually bewitched who, when the truth as it is in Jesus is plainly set before them, will not thus obey it. Several things proved and aggravated the folly of these Christians.
Gal 3:6-18
The apostle having reproved the Galatians for not obeying the truth, and endeavoured to impress them with a sense of their folly herein, in these verses he largely proves the doctrine which he had reproved them for rejecting, namely, that of justification by faith without the works of the law. This he does several ways.
Gal 3:19-29
The apostle having just before been speaking of the promise made to Abraham, and representing that as the rule of our justification, and not the law, lest they should think he did too much derogate from the law, and render it altogether useless, he thence takes occasion to discourse of the design and tendency of it, and to acquaint us for what purposes it was given. It might be asked, "If that promise be sufficient for salvation, wherefore then serveth the law? Or, Why did God give the law by Moses?' To this he answers,
The apostle adds that the law was given for this purpose till the seed should come to whom the promise was made; that is, either till Christ should come (the principle seed referred to in the promise, as he had before shown), or till the gospel dispensation should take place, when Jews and Gentiles, without distinction, should, upon believing, become the seed of Abraham. The law was added because of transgressions, till this fulness of time, or this complete dispensation, should come. But when the seed came, and a fuller discovery of divine grace in the promise was made, then the law, as given by Moses, was to cease; that covenant, being found faulty, was to give place to another, and a better, Heb. 8:7, 8. And though the law, considered as the law of nature, is always in force, and still continues to be of use to convince men of sin and to restrain them from it, yet we are now no longer under the bondage and terror of that legal covenant. The law then was not intended to discover another way of justification, different from that revealed by the promise, but only to lead men to see their need of the promise, by showing them the sinfulness of sin, and to point them to Christ, through whom alone they could be pardoned and justified.
As a further proof that the law was not designed to vacate the promise, the apostle adds, It was ordained by angels in the hand of a mediator. It was given to different persons, and in a different manner from the promise, and therefore for different purposes. The promise was made to Abraham, and all his spiritual seed, including believers of all nations, even of the Gentiles as well as the Jews; but the law was given to the Israelites as a peculiar people, and separated from the rest of the world. And, whereas the promise was given immediately by God himself, the law was given by the ministry of angels, and the hand of a mediator. Hence it appeared that the law could not be designed to set aside the promise; for (v. 20), A mediator is not a mediator of one, of one party only; but God is one, but one party in the promise or covenant made with Abraham: and therefore it is not to be supposed that by a transaction which passed only between him and the nation of the Jews he should make void a promise which he had long before made to Abraham and all his spiritual seed, whether Jews or Gentiles. This would not have been consistent with his wisdom, nor with his truth and faithfulness. Moses was only a mediator between God and the spiritual seed of Abraham; and therefore the law that was given by him could not affect the promise made to them, much less be subversive of it.
