25 Hosea put it well: I'll call nobodies and make them somebodies; I'll call the unloved and make them beloved. 26 In the place where they yelled out, "You're nobody!" they're calling you "God's living children." 27 Isaiah maintained this same emphasis: If each grain of sand on the seashore were numbered and the sum labeled "chosen of God," They'd be numbers still, not names; salvation comes by personal selection. 28 God doesn't count us; he calls us by name. Arithmetic is not his focus. 29 Isaiah had looked ahead and spoken the truth: If our powerful God had not provided us a legacy of living children, We would have ended up like ghost towns, like Sodom and Gomorrah.

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.
