How do we know God's sovereign choice in salvation is true?

Scripture clearly teaches that God's sovereign choice in salvation is foundational to the doctrine of grace. In Ephesians 1:4, Paul notes that God 'chose us in Him before the foundation of the world,' emphasizing that His election is not based on foreseen faith or merit but solely on His grace. This teaching is consistent throughout the Scriptures and reassures believers that salvation is a work initiated and completed by God, ensuring that no one can boast in their own works but must rely solely on the sovereign grace of God. Such sovereignty underscores our assurance and hope in Christ's redemptive work.
