Romans 11:5-6, 25-27

And that is but one example of what God is doing in this age of fulfillment, for God’s grace empowers his chosen remnant. And since it is by God’s grace, it can’t be a matter of their good works; otherwise, it wouldn’t be a gift of grace, but earned by human effort.

My beloved brothers and sisters, I want to share with you a mystery concerning Israel’s future. For understanding this mystery will keep you from thinking you already know everything. A partial and temporary hardening to the gospel has come over Israel, which will last until the full number of non-Jews has come into God’s family. And then God will bring all of Israel to salvation! The prophecy will be fulfilled that says: “Coming from Zion will be the Savior, and he will turn Jacob away from evil. For this is my covenant promise with them when I forgive their sins.”
