GRACE Romans 11:5-6

So too, at the present time there is a remnant chosen by grace. And if by grace, then it cannot be based on works; if it were, grace would no longer be grace.

So too, at the present time there is a remnant 
Romans 9:27-28  Isaiah cries out concerning Israel: "Though the number of the Israelites be like the sand by the sea, only a remnant will be saved. For the Lord will carry out his sentence on earth with speed and finality." (Isaiah 10:22-23)

chosen by grace 
Romans 3:21-24  But now apart from the law the righteousness of God has been made known to which the Law and the Prophets testify. This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile, for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus.

And if by grace, then it cannot be based on works 
Romans 4:4  Now to the one who works, wages are not credited as a gift but as an obligation.
Romans 9:30-33  What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but the people of Israel, who pursued the law as the way of righteousness, have not attained their goal. Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the stumbling stone. As it is written: "See, I lay in Zion a stone that causes people to stumble and a rock that makes them fall, and the one who believes in him will never be put to shame." (Isaiah 8:14; 28:16)
