How do we know that Christians are predestined for salvation?

The doctrine of predestination is grounded in Scripture, specifically Ephesians 1:4-5, which reveals that God chose us in Christ before the foundation of the world, predestining us for adoption as His children. This theological perspective affirms that salvation is entirely the work of God, emphasizing His sovereignty in the process. Paul’s epistles consistently underline that God acts according to His own will and purpose, particularly in choosing those who would inherit His grace. This ensures that no one can boast about their own works, as salvation is purely a result of God's sovereign grace and mercy. Such a truth instills confidence in believers, affirming the certainty of their salvation as they recognize it as rooted in God’s eternal plan.
