Romans 11:5-6, 25-27

It is the same today, for a few of the people of Israel have remained faithful because of God’s grace—his undeserved kindness in choosing them. And since it is through God’s kindness, then it is not by their good works. For in that case, God’s grace would not be what it really is—free and undeserved.

I want you to understand this mystery, dear brothers and sisters, so that you will not feel proud about yourselves. Some of the people of Israel have hard hearts, but this will last only until the full number of Gentiles comes to Christ. And so all Israel will be saved. As the Scriptures say, “The one who rescues will come from Jerusalem, and he will turn Israel away from ungodliness. And this is my covenant with them, that I will take away their sins.”
