What does the Bible say about God's election of grace?

In Romans 11, Paul addresses the question of whether God has cast away His people, the Israelites. He affirms that God has not rejected them entirely, as He has reserved a remnant according to the election of grace (Romans 11:5). This means that out of the whole, there are those whom God has chosen to save, demonstrating His sovereignty and grace in salvation. The concept of election emphasizes that God's choice is not based on human merit but solely on His divine will and purpose, as seen in Ephesians 1:4-5, where it states that believers were chosen in Christ before the foundation of the world.
