How do we know that election is unconditional?

The doctrine of unconditional election teaches that God's choice of whom to save is not based on foreseen faith or good works but solely on His divine will and purpose. Paul teaches that God has chosen His people before the foundation of the world (Ephesians 1:4). The example of Israel illustrates this point, as God chose His people based not on their merit but on His love and purpose (Jeremiah 31:3). Thus, the security of salvation rests entirely on God’s sovereignty, demonstrating His unmatched grace and authority.
