Romans 11:7
7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded
Commentaries
"What then? Israel hath not obtained that, which he seeketh for; but the election hath obtained it and the rest were blinded."
He had said that God did not cast off His people; and to show in what sense He had not cast them off, he takes refuge in the Prophets again. And having shown by them that the more part of the Jews were lost, that he might not seem to be again bringing forward an accusation of his own, and to make his discourse offensive, and to be attacking them as enemies, he takes refuge in David and Isaiah. Having then mentioned the state of things in Elijah's time, and shown what grace is, he proceeds, "What then? Israel hath not obtained that which he seeketh for." Now this is as much what an accuser would say, as what one who was putting a question. For the Jew, he means, is inconsistent with himself when he seeketh for righteousness, which he will not accept. Then to leave them with no excuse, he shows, from those who have accepted it, their unfeeling spirit, as he says, "But the election hath obtained it," and they are the condemnation of the others. And this is what Christ says, "But if I by Beelzebub cast out devils, by whom do your children cast them out? Wherefore they shall be your judges." For to prevent any one from accusing the nature of the thing, and not their own temper, he points out those who had obtained it. Hence he uses the word with great propriety, to show at once the grace from above and the zeal of these. For it is not to deny free-will that he speaks of their having "obtained" it, but to show the greatness of the good things, and that the greater part was of grace, though not the whole. For we too are in the habit of saying, "so and so chanced to get," "so and so met with," when the gain has been a great one. Because it is not by man's labors, but by God's gift, that the greater part was brought about.
"And the rest was blinded."
See how he has been bold enough to tell with his own voice the casting off of the rest. For he had indeed spoken of it already, but it was by bringing the prophets in as accusers. But from this point he declares it in his own person. Still even here he is not content with his own declaration, but brings Isaiah the prophet in again. For after saying, "were blinded," he proceeds; "according as it is written, God hath given them the spirit of slumber."

Israel as a whole has not obtained righteousness because it did not seek it by faith but thought that it was justified solely by works of the law, even though it disregarded the greatest commandments of the law. That is why the Savior censures those who strain at a gnat but swallow a camel.

Israel tried to find righteousness in the type which was the law but did not obtain it. However, those who were sealed were elected and did obtain it on account of their belief, being justified by their faith. The rest were blinded, being hardened and rebellious.

The elect are those who believed.… The rest were hardened because of their unbelief.
Source: INTERPRETATION OF THE LETTER TO THE ROMANS
Having explained what grace is, that is, that it is a gift of God apart from works, he says that the Israelites, seeking righteousness, did not obtain it, because they sought it poorly and from works, by which it is impossible to obtain it. "But the elect obtained it." By the word "obtained" he shows the greatness of the blessings and that everything is the work of God's grace. And in ordinary conversation we too say: he obtained a profit, that is, he acquired a gain without labor.

Then when he says, what then, he draws the conclusion he intended.
And first he sets it out, saying what then shall we say follows from what has been said? This, namely, that Israel, as far as the greater part of its people was concerned, has not obtained that which it sought, namely, justice. This is the way one must interpret what was said above: but Israel, by following after the law of justice, is not come unto the law of justice (Rom 9:31). You shall seek me, and shall not find me (John 7:34).
Nevertheless, the election, i.e., the elect of the Jews, has obtained it: he chose us in him, that we should be holy (Eph 1:4). But the rest, i.e., the remainder of the people, have been blinded because of their malice: their own malice blinded them (Wis 1:22).
