25 Concerning the Gentiles, God says in the prophecy of Hosea, "Those who were not my people, I will now call my people. And I will love those whom I did not love before." 26 And, "Then, at the place where they were told, 'You are not my people,' there they will be called 'children of the living God.'" 27 And concerning Israel, Isaiah the prophet cried out, "Though the people of Israel are as numerous as the sand of the seashore, only a remnant will be saved. 28 For the Lord will carry out his sentence upon the earth quickly and with finality." 29 And Isaiah said the same thing in another place: "If the Lord of Heaven's Armies had not spared a few of our children, we would have been wiped out like Sodom, destroyed like Gomorrah."
30 What does all this mean? Even though the Gentiles were not trying to follow God's standards, they were made right with God. And it was by faith that this took place. 31 But the people of Israel, who tried so hard to get right with God by keeping the law, never succeeded. 32 Why not? Because they were trying to get right with God by keeping the law instead of by trusting in him. They stumbled over the great rock in their path. 33 God warned them of this in the Scriptures when he said, "I am placing a stone in Jerusalem that makes people stumble, a rock that makes them fall. But anyone who trusts in him will never be disgraced."

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.
