Why is the concept of a remnant important for Christians?

The concept of a remnant is crucial in understanding God's faithfulness to His covenant promises. In biblical history, even when the majority of Israelites turned away from God, a small remnant was always preserved. This is seen in both the Old and New Testaments, where God promises to save a remnant according to His grace (Isaiah 10:22, Romans 9:27). For Christians, this assures us that God's grace extends to those He has chosen and elected, demonstrating that our hope lies not in human efforts but in His sovereign will.
