How do we know that God predestined some for salvation?

The doctrine of predestination and election is firmly rooted in scripture, particularly in Ephesians 1:4-5, which states that God chose us in Him before the foundation of the world. This implies that God's choice for salvation is not based on foreseen faith or actions but is purely a work of His sovereign grace. It emphasizes the total depravity of humanity and the necessity of divine intervention for redemption. This election is part of God’s eternal plan and reflects His mercy and sovereign authority over salvation.
