How do we know that election is true according to scripture?

The certainty of election arises from scripture's consistent affirmation of God's sovereign choice in salvation. In Romans 9, Paul discusses God's prerogative to choose whom He wills for His purposes, illustrated by the examples of Jacob and Esau. This illustrates that God’s grace is not based on human merit but rather on His divine purpose. Additionally, passages like Ephesians 1:4-5 affirm that believers were chosen in Christ before the foundation of the world, reflecting the unchanging nature of God's grace towards His elect.
