27Isaiah cries out concerning Israel, "though the number of the sons of israel be like the sand of the sea, it is the remnant that will be saved; 28for the Lord will execute his word on the earth, thoroughly and quickly." 29And just as Isaiah foretold, "unless the Lord of sabaoth had left to us a posterity, we would have become like sodom, and would have resembled gomorrah." 30What shall we say then? That Gentiles, who did not pursue righteousness, attained righteousness, even the righteousness which is by faith; 31but Israel, pursuing a law of righteousness, did not arrive at that law. 32Why? Because they did not pursue it by faith, but as though it were by works. They stumbled over the stumbling stone, 33just as it is written, "behold, I lay in zion a stone of stumbling and a rock of offense, and he who believes in Him will not be disappointed."
