How do we know that God's choosing is sovereign?

Sovereign grace theology emphasizes that God’s choice is not based on human merit but entirely on His own will and purpose. Romans 9:13 explicitly states, 'Jacob have I loved, but Esau have I hated,' which illustrates God's sovereign choice in salvation. This demonstrates that God's election is rooted in His grace rather than human action or worthiness. Jacob's life serves as a reminder that even the least worthy are recipients of God's sovereign grace, affirming that our standing with God is determined by His mercy alone, not by our deeds.
