How do we know that God's elect are chosen before the world began?

Ephesians chapter 1 provides a clear declaration of God's sovereign choice. It states that He chose us in Christ before the foundation of the world, demonstrating that God's election is not based on foreseen faith or merit but solely on His purposes and grace. This doctrine of election reassures believers of their security in salvation, as those chosen by God will be preserved and brought to faith in due time. The implications of this doctrine alleviate concerns about human ability to maintain salvation, underscoring that it is God’s work from start to finish.
