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

The doctrine of election is foundational within Reformed theology, asserting that God, in His sovereignty, has chosen certain individuals for salvation before the foundation of the world. This is evidenced in Romans 9:11-16, which states that God's purpose in election might stand, not of works, but of Him who calls. Here, the example of Jacob and Esau illustrates that God's choice is based entirely on His mercy and purpose, rather than human merit. Furthermore, Ephesians 1:4-5 emphasizes that believers are chosen in Christ before the world's foundations, affirming that our salvation is a result of God's sovereign grace, ultimately to the praise of His glorious grace.
