Romans 9:25-26, 30-33

Just as He says in [the writings of the prophet] Hosea: “I WILL CALL THOSE WHO WERE NOT MY PEOPLE, ‘MY PEOPLE,’ AND [I will call] HER WHO WAS NOT BELOVED, ‘BELOVED.’ ” [Hos 2:23] “AND IT SHALL BE THAT IN THE PLACE WHERE IT WAS SAID TO THEM, ‘YOU ARE NOT MY PEOPLE,’ THERE THEY SHALL BE CALLED SONS OF THE LIVING GOD.” [Hos 1:10]

What shall we say then? That Gentiles, who did not pursue righteousness [who did not seek salvation and a right relationship with God, nevertheless] obtained righteousness, that is, the righteousness which is produced by faith; whereas Israel, [though always] pursuing the law of righteousness, did not succeed in fulfilling the law. [Is 51:1] And why not? Because it was not by faith [that they pursued it], but as though it were by works [relying on the merit of their works instead of their faith]. They stumbled over the stumbling Stone [Jesus Christ]. [Is 8:14; 28:16] As it is written and forever remains written, “BEHOLD I AM LAYING IN ZION A STONE OF STUMBLING AND A ROCK OF OFFENSE; AND HE WHO BELIEVES IN HIM [whoever adheres to, trusts in, and relies on Him] WILL NOT BE DISAPPOINTED [in his expectations].” [Is 28:16]
