Galatians 4:21

One should note that the whole narrative in Genesis is here called Law, not, according to the popular assumption, simply statements of what is to be done or avoided but everything that is rehearsed concerning Abraham and his wives and sons.

Nay, verily, the Holy Spirit is not given by measure, but is poured out altogether on the believer. For if the day rises alike to all, and if the sun is diffused with like and equal light over all, how much more does Christ, who is the true sun and the true day, bestow in His Church the light of eternal life with the like equality! Of which equality we see the sacrament celebrated in Exodus, when the manna flowed down from heaven, and, prefiguring the things to come, showed forth the nourishment of the heavenly bread and the food of the coming Christ. For there, without distinction either of sex or of age, an omer was collected equally by each one. Whence it appeared that the mercy of Christ, and the heavenly grace that would subsequently follow, was equally divided among all; without difference of sex, without distinction of years, without accepting of persons, upon all the people of God the gift of spiritual grace was shed. Assuredly the same spiritual grace which is equally received in baptism by believers, is subsequently either increased or diminished in our conversation and conduct; as in the Gospel the Lord's seed is equally sown, but, according to the variety of the soil, some is wasted, and some is increased into a large variety of plenty, with an exuberant fruit of either thirty or sixty or a hundred fold. But, once more, when each was called to receive a penny, wherefore should what is distributed equally by God be diminished by human interpretation?

He says rightly, "ye that desire," for the matter was not one of a proper and orderly succession of things but of their own unseasonable contentiousness. It is the Book of Creation which he here calls the Law, which name he often gives to the whole Old Testament.

After he had already sufficiently softened them and drawn them to himself, he again enters into dispute, pointing out that the law itself does not wish to be observed: answer me, he says. He also said beautifully: "those who desire," because such a situation depended …

Above, the Apostle showed the pre-eminence of grace by a human example; here he proves it on the authority of the Scripture. First, he proposes a fact; Secondly, he expounds its mystery (v. 24); Thirdly, he concludes his proposition (v. 31). As to the first, …

Tell me, ye that desire to be under the law,....

Just as the extra-ordinarily-born Isaac, the gift of grace according to promise, supplanted, beyond all human calculations, the naturally-born Ishmael, so the new theocratic race, the spiritual seed of Abraham by promise, the Gentile, as well as Jewish believers, were about to take the place of the natural seed, who had imagined that to them exclusively belonged the kingdom of God.

Ye that desire to be under the law - Ye who desire to incorporate the Mosaic institutions with Christianity, and thus bring yourselves into bondage to circumcision, and a great variety of oppressive rites. Do ye not hear the law? - Do ye not understand what is written in the Pentateuch relative to Abraham and his children. It is evident that the word law is used in two senses in this verse. It first means the Mosaic institutions; secondly, the Pentateuch, where the history is recorded to which the apostle refers.

Tell me ... - In order to show fully the nature and the effect of the Law, Paul here introduces an illustration from an important fact in the Jewish history. This allegory has given great perplexity to expositors, and, in some respects, it is attended with real difficulty. An examination of the difficulties will be found in the larger commentaries. My object, without examining the expositions which have been proposed, will be to state, in as few words as possible, the simple meaning and design of the allegory. The design it is not difficult to understand.
