How does salvation highlight God's sovereignty?

The doctrine of salvation showcases God's sovereignty in that it is entirely dependent on Him, as stated in Philippians 2:13, where it says, 'for it is God which worketh in you to will and to do of his good pleasure.' This emphasizes the truth that salvation is not initiated by human will or effort, but by the divine will of God. Additionally, Romans 9:16 explicitly states that salvation is not dependent on human effort ('not of him that willeth, nor of him that runneth'), but solely on God's mercy. Therefore, the work of salvation magnifies God's authority and His initiative in redeeming His people.
