Римлянам 9:27

Esaias also crieth--"But Isaiah crieth"--an expression denoting a solemn testimony openly borne (Joh 1:15; Joh 7:28, Joh 7:37; Joh 12:44; Act 23:6; Act 24:21). concerning Israel, Though the number of the children--"sons" of Israel be as the sand of the sea, a--"the" remnant--that is, the elect remnant only shall be saved.

We have here the apostle's solemn profession of a great concern for the nation and people of the Jews - that he was heartily troubled that so many of them were enemies to the gospel, and out of the way of salvation. For this he had great heaviness and continual sorrow. Such a profession as this was requisite to take off the odium which otherwise he might have contracted by asserting and proving their rejection. It is wisdom as much as may be to mollify those truths which sound harshly and seem unpleasant: dip the nail in oil, it will drive the better. The Jews had a particular pique at Paul above any of the apostles, as appears by the history of the Acts, and therefore were the more apt to take things amiss of him, to prevent which he introduces his discourse with this tender and affectionate profession, that they might not think he triumphed or insulted over the rejected Jews or was pleased with the calamities that were coming upon them. Thus Jeremiah appeals to God concerning the Jews of his day, whose ruin was hastening on (Jer 17:16), Neither have I desired the woeful day, thou knowest. Nay, Paul was so far from desiring it that he most pathetically deprecates it. And lest this should be thought only a copy of his countenance, to flatter and please them, I. He asserts it with a solemn protestation (Rom 9:1): I say the truth in Christ, "I speak it as a Christian, one of God's people, children that will not lie, as one that knows not how to give flattering title." Or, "I appeal to Christ, who searches the heart, concerning it." He appeals likewise to his own conscience, which was instead of a thousand witnesses. That which he was going to assert was not only a great and weighty thing (such solemn protestations are not to be thrown away upon trifles), but it was likewi…

9:27-28 only a remnant will be saved: So many Israelites had turned from God that the Old Testament prophets spoke of a true spiritual Israel within the larger nation of Israel (see Isa 11:10-16). The remnant would receive salvation, while the rest of the Israelites would suffer condemnation.
