How are some people chosen for salvation according to the Bible?

Biblical theology asserts that God’s election is not based on foreseen faith or works, but rather on His sovereign will. Ephesians 1:4-5 declares, 'He chose us in Him before the foundation of the world,' emphasizing that God's choice is unconditional. Similarly, Romans 9 illustrates that God loves some (Jacob) and hates others (Esau) according to His divine purpose. This concept of predestination highlights the grace of God, who, in His mercy, selects certain individuals to receive salvation, thus denying any human basis for boasting or entitlement.
