How do we know God has a chosen people?

Ephesians 1:4-5 explicitly states, 'According as He hath chosen us in Him before the foundation of the world, that we should be holy and without blame before Him in love.' This doctrine of election is rooted in God's eternal purpose and underscores His sovereignty in salvation. Recognizing that believers are chosen affirms that their salvation is part of God's divine plan and is grounded in His will and not in human merit. This truth serves as a profound comfort, assuring believers of their security in Christ.
