How do we know God's choice of Jacob is true?

The assertion of God's choice of Jacob over Esau is rooted in the doctrine of election, vividly illustrated in Romans 9:13, where it states, 'Jacob have I loved, but Esau have I hated.' This divine choice emphasizes God's sovereignty and His right to choose whom He wills, independent of individual merit or action. Throughout Scripture, instances like Jacob's life story outline the transformative power of God's grace, demonstrating that His selection is not based on human standards or worthiness but on His own purposes and grace. This reality reassures believers that their salvation and standing before God are based entirely on God's initiative rather than their achievements, reinforcing the historic Reformed understanding of salvation by grace alone.
