What does the Bible say about God's purpose and election?

In Romans 9:10-12, we see that the Apostle Paul explains God's sovereign purpose of election through the example of Jacob and Esau, who were chosen before they were born and before they had done any good or evil. This illustrates that God's purpose in election is not based on any human merit or works, but entirely on His sovereign will. The distinction made between Jacob, whom God loved, and Esau, whom He hated, emphasizes that God's election is rooted in His own divine purpose, demonstrating His sovereignty in salvation. Therefore, it underscores the truth that not all who are biological descendants of Abraham are true heirs of the promise; rather, it is those chosen by God's purpose who are considered spiritual Israel.
