How do we know election according to God's purpose is true?

Election, as articulated in Romans 9:11, demonstrates that God's choice of individuals for salvation is not based on their works but on His purpose and calling. Scripture affirms that before the twins, Jacob and Esau, were born, God had chosen Jacob 'according to election' to fulfill His divine purpose. This doctrine is echoed throughout the New Testament, showing that God's elect are chosen in Christ before the foundation of the world (Ephesians 1:4), revealing that His plans are sovereign and purposeful.
