How do we know God's sovereignty is true in salvation?

God's sovereignty in salvation is a central tenet of Reformed theology, evidenced by numerous Scriptures that illustrate His control over election and redemption. Romans 8:29-30 outlines the process of salvation as being predestined by God: 'For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.' This chain of salvation—foreknowledge, predestination, calling, justification, and glorification—demonstrates that God's purpose cannot be thwarted and that He alone initiates and completes the work of salvation according to His will. Sovereignty assures us that our salvation rests not on human effort but on God's unchanging promise.
