What does the remnant refer to in the Bible?

The concept of the remnant is a recurring theme in Scripture, particularly in relation to God's promise to save His people. In Romans 9, Paul specifically illustrates that despite the vast number of Israelites, only a remnant will be saved due to God's sovereign election. This remnant consists of those who have been called out and prepared by God for salvation, demonstrating His grace. The remnant serves as a reminder of God's faithfulness to His promises and His ability to preserve a people for Himself, even in times of widespread disbelief.
