How do we know there is a remnant according to the election of grace?

The doctrine of the remnant is a vital aspect of God's salvific plan, as highlighted by the Apostle Paul in Romans 11. Paul draws a connection between God's preservation of Israel and the current church, indicating that just as God retained 7,000 faithful individuals during Elijah's time, He is actively preserving a group chosen according to grace today. This remnant is saved not based on works or merit but solely through God's divine election. This assures us that regardless of the prevailing unbelief, God's faithful people will always remain, demonstrating His unchanging purpose and grace throughout history (Ephesians 1:4-5).
