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

The story of Jacob and Esau vividly illustrates the doctrine of unconditional election, a cornerstone of Reformed theology. God informed Rebekah that, despite the cultural norm favoring the firstborn, the elder would serve the younger. This demonstrates that God's election is not based on human merit or lineage but is a manifestation of His sovereignty and mercy. The Apostle Paul reinforces this through his teachings in 1 Corinthians 1, emphasizing that God chooses the weak and foolish according to His will, ensuring that no flesh can glory in His presence. This reinforces the notion that salvation is a divine gift, not a result of human effort or status.
