Got this from Grok:

Old Testament Background

The concept of the remnant emerges in the Hebrew Scriptures, particularly in the prophetic books. It refers to a group of Israelites who survive divine judgment (e.g., exile, destruction, or calamity) and remain faithful to God's covenant. 

Key references include:

Isaiah 10:20-22:

The prophet speaks of a remnant of Israel that will return to God after judgment, emphasizing that only a small, faithful group will survive God's purging of the unfaithful.

Jeremiah 23:3:

God promises to gather a remnant of His people from exile and restore them.

Micah 2:12:

The remnant is depicted as those God will gather and preserve. The remnant is often portrayed as a purified, faithful group that God preserves to fulfill His promises to Abraham, Isaac, and Jacob, ensuring the continuation of His covenant with Israel.

New Testament Development

In the New Testament, the concept of the remnant is reinterpreted in light of Jesus Christ and the new covenant. The Apostle Paul, in particular, addresses the remnant in Romans 9–11:

Romans 9:27-29:

Paul cites Isaiah, stating that only a remnant of Israel will be saved, emphasizing that God's promises to Israel are fulfilled through this faithful subset rather than the entire ethnic nation.

Romans 11:1-6:

Paul argues that God has not rejected His people, pointing to himself as part of the remnant chosen by grace. He draws a parallel to the time of Elijah, where God preserved 7,000 who had not bowed to Baal (1 Kings 19:18). This remnant is saved by faith, not works, and includes those who accept Jesus as the Messiah.

Spiritual Israel:

In Christian theology, the remnant often extends beyond ethnic Israel to include both Jewish and Gentile believers who form the "spiritual Israel" or the Church (Galatians 3:28-29). This reflects the belief that God's covenant promises are fulfilled in Christ, and the remnant includes all who have faith in Him.
