How do we know that God predestines people for salvation?

The doctrine of predestination is rooted in the belief that God, in His sovereign will, has chosen certain individuals for salvation before the foundation of the world. Ephesians 1:4-5 states, 'just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will.' This reveals that predestination is part of God's eternal plan, underscoring His authority over salvation and the assurance that it is not based on human merit. Furthermore, Romans 8:29-30 elaborates on this process, explaining that those whom He predestines, He also calls, justifies, and glorifies. This chain of salvation affirms God’s control and intentionality in bringing His people to faith.
