How do we know salvation is God's prerogative?

The doctrine of salvation as God's prerogative is rooted in passages like Ephesians 1:4-5, which states that He chose us in Him before the foundation of the world. This fundamental principle highlights that our salvation is contingent upon God's sovereign will rather than our actions or decisions. In this context, the Arminian view, which emphasizes human choice, falls short of the biblical truth that it is God alone who effects salvation. Without divine election, none could be saved, reiterating that grace is a gift given freely by God.
