God Has Always Had A Remnant
God’s promises to Israel did not mean that all Jews were locked in to salvation no matter how sinful and disobedient they were. It did not mean that an unbelieving and disobedient Jew was acceptable to God simply because he had been born a Jew. God’s promises were intended for those who believed and obeyed Him. The people who believed and obeyed Him have always been “His people.”
In every generation of the church “a remnant chosen by grace” has been called from among the Jews. Paul added that this choice is totally by God’s grace (cf. Eph. 2:8–9) and he emphasized the antithesis between grace and works (cf. Rom. 4:4–5; 9:30–32).
God’s Word affirms a continuing role for Israel in salvation history. But Israel cannot claim this role as a matter of right, for it is due solely to the working of God’s grace.
Some Jews made the mistake of assuming that God’s election of Israel virtually guaranteed spiritual benefits to every member of the nation. Birth into that nation, circumcision (for males), and a reasonable faithfulness in observing the law were all that was needed to ensure one’s salvation. Some segments of the church have much the same kind of attitude. People assume that they will go to heaven as long as they can claim such external credits as baptism, confirmation, church attendance, participation in the mass, and acts of service.
