What is the remnant in Romans 11?

In Romans 11, Paul addresses the concept of a remnant, which signifies those individuals within Israel who have received God's grace and believed in the gospel. This remnant is according to the election of grace, showing that not all of physical Israel is saved, but a specific group has been foreordained by God for salvation. This serves as a reminder that true Israel comprises those who have been spiritually awakened and accept Christ, thus highlighting the nature of God's redemptive plan throughout history.
