How do we know that salvation is fully God's work?

The doctrine of salvation being fully God's work is clearly articulated in Scripture. Romans 8:29-30 outlines the golden chain of redemption, wherein God foreknows, predestines, calls, justifies, and glorifies His people, ensuring that every aspect of salvation is orchestrated by Him. It emphasizes that it is not through human effort or decision, but through God's sovereign will and grace that individuals are saved. Furthermore, statements such as 'salvation belongs unto the Lord' echo throughout the Bible, reinforcing the idea that every gift—faith, repentance, and righteousness—is granted by God. Therefore, true worship recognizes that we contribute nothing to our salvation but receive it as an unmerited gift from our gracious God.
