Why is the concept of a remnant important in the Bible?

The remnant is a recurring theme throughout the Bible, representing those who remain faithful to God despite widespread unfaithfulness. In Micah, there is assurance that even amidst judgment, God will preserve a remnant of His people. This remnant points to the elect, chosen by grace, and signifies God's sovereignty in salvation. It serves as a reminder that while many may fall away, His purpose prevails through those He elects, reflecting the continuous thread of God's redemptive plan culminating in Christ.
