25 As indeed he says in Hosea, "Those who were not my people I will call 'my people,' and her who was not beloved I will call 'beloved.'" 26 "And in the very place where it was said to them, 'You are not my people,' there they will be called 'sons of the living God.'" 27 And Isaiah cries out concerning Israel: "Though the number of the sons of Israel[1] be as the sand of the sea, only a remnant of them will be saved, 28 for the Lord will carry out his sentence upon the earth fully and without delay." 29 And as Isaiah predicted, "If the Lord of hosts had not left us offspring, we would have been like Sodom and become like Gomorrah."
30 What shall we say, then? That Gentiles who did not pursue righteousness have attained it, that is, a righteousness that is by faith; 31 but that Israel who pursued a law that would lead to righteousness[2] did not succeed in reaching that law. 32 Why? Because they did not pursue it by faith, but as if it were based on works. They have stumbled over the stumbling stone, 33 as it is written, "Behold, I am laying in Zion a stone of stumbling, and a rock of offense; and whoever believes in him will not be put to shame."

Commentary on Romans 9:25-29
(Read Romans 9:25-29)
The rejecting of the Jews, and the taking in the Gentiles, were foretold in the Old Testament. It tends very much to the clearing of a truth, to observe how the Scripture is fulfilled in it. It is a wonder of Divine power and mercy that there are any saved: for even those left to be a seed, if God had dealt with them according to their sins, had perished with the rest. This great truth this Scripture teaches us. Even among the vast number of professing Christians it is to be feared that only a remnant will be saved.
Commentary on Romans 9:30-33
(Read Romans 9:30-33)
The Gentiles knew not their guilt and misery, therefore were not careful to procure a remedy. Yet they attained to righteousness by faith. Not by becoming proselytes to the Jewish religion, and submitting to the ceremonial law; but by embracing Christ, and believing in him, and submitting to the gospel. The Jews talked much of justification and holiness, and seemed very ambitious to be the favourites of God. They sought, but not in the right way, not in the humbling way, not in the appointed way. Not by faith, not by embracing Christ, depending upon Christ, and submitting to the gospel. They expected justification by observing the precepts and ceremonies of the law of Moses. The unbelieving Jews had a fair offer of righteousness, life, and salvation, made them upon gospel terms, which they did not like, and would not accept. Have we sought to know how we may be justified before God, seeking that blessing in the way here pointed out, by faith in Christ, as the Lord our Righteousness? Then we shall not be ashamed in that awful day, when all refuges of lies shall be swept away, and the Divine wrath shall overflow every hiding-place but that which God hath prepared in his own Son.
