How do we know Election is true in the story of Esau and Jacob?

The narrative of Jacob and Esau is a powerful example of divine election as explained in Romans 9, where Paul states that before they were born or had done any good or evil, God chose Jacob over Esau. This choice was made to demonstrate that salvation is not based on human actions or merits but rests solely on God's sovereign will. Esau's rejection highlights a broader theological truth that God's mercy and grace are not granted universally, but selectively, according to His purpose and plan. This doctrine reassures believers of God's sovereignty over all aspects of salvation, validating the concept of grace as the foundation for God's love.
