How do we know God's sovereignty in saving sinners?

The concept of God's sovereignty in salvation is rooted in His eternal purpose, as seen in the prophecy of Cyrus in Isaiah 44. Even before the captivity of the Jews, God had arranged for a deliverer, illustrating that He acts independently of human will. This typology points to Christ, who was predestined to save His people from their sins. Scripture supports that before we fell into sin, God had already provided salvation through His Son, highlighting His complete authority over the salvation process.
