Galatians 3:17

Then when he says, "Now this I say: that the testament which was confirmed by God," he draws his conclusion. Here let us see, in order, what it is that he says. He says therefore that this is what God promised to Abraham. But this …

And this I say - What I mean is this. The covenant which was before confirmed of God - By the promise itself, by the repetition of it, and by a solemn oath, concerning the blessing all nations. Through Christ, the law which was four hundred and thirty years after - Counting from the time when the promise was first made to Abraham, Gen. xii, 2, 3.

And this I say,....

The covenant which was confirmed before of God - By God, in his promise to Abraham. It was confirmed before the giving of the Law. The confirmation was the solemn promise which God made to him. In Christ - With respect to the Messiah; a covenant relating to him, and which promised that he should descend from Abraham. The word “in,” in the phrase “in Christ,” does not quite express the meaning of the Greek εἰς Χριστὸν eis Christon. That means rather “unto Christ;” or unto the Messiah; that is, the covenant had respect to him.

Here Jacob received the promise of the blessing, for which God had called Abraham out of Ur, repeated for the last time, on the last night of his sojourn in the land of promise. cannot--Greek, "doth not disannul." make . . . of none effect--The promise would become so, if the power of conferring the inheritance be transferred from it to the law (Ro 4:14).

Confirmed before of God in Christ - i.e. The promise of justification, etc., made to believers in Christ Jesus, who are the spiritual seed of Christ, as they are children of Abraham, from the similitude of their faith. Abraham believed in God, and it was reckoned to him for justification; the Gentiles believed in Christ, and received justification. Probably the word Christ is to be taken, both here and in the preceding verse, for Christians, as has already been hinted. However it be taken, the sense is plainly the same; the promise of salvation must necessarily be to them who believe in Christ, for he is the promised seed, Gen 3:15, through whom every blessing is derived on mankind; and through his spiritual seed - the true Christians, the conquests of the cross are daily spreading over the face of the earth. The present unparalleled dispersion of the sacred writings, in all the regular languages of the universe, is a full proof that all the nations of the earth are likely to be blessed through them; but they have nothing but what they have received from and through Christ. Four hundred and thirty years after - God made a covenant with Abraham that the Messiah should spring from his posterity. This covenant stated that justification should be obtained by faith in the Messiah. The Messiah did not come till 1911 years after the making of this covenant, and the law was given 430 years after the covenant with Abraham, therefore the law, which was given 1481 years before the promise to Abram could be fulfilled, (for so much time elapsed between the giving of the law and the advent of Christ), could not possibly annul the Abrahamic covenant. This argument is absolute and conclusive. Let us review it. The promise to Abraham respects the Messiah, and cannot be fulfilled but in him. […]
