How do we know God chooses to save some people?

God’s choosing of certain individuals for salvation is a central tenet in the sovereign grace theology, emphasizing His sovereignty and mercy. Ephesians 1:4-5 states that He chose us in Him before the foundation of the world, highlighting that our salvation is rooted in God’s eternal purpose and not on our merit. This doctrine, often referenced through the historical Five Points of Dordrecht, underlines that salvation is an act of divine grace where God, in His sovereignty, extends mercy to sinners who have no ability to save themselves. It illustrates God’s unfolding plan through history for His own glory, as seen in Romans 9:15-16, where God has mercy on whom He wills.
