How do we know that salvation is entirely a work of God?

The doctrine of salvation being a work of God is foundational to sovereign grace theology. Jonah 2:9 states, 'Salvation is of the Lord,' highlighting that it is God's initiative and actions that secure our redemption. Scripture reinforces this by declaring that our salvation is not contingent upon our works but fully reliant on God's grace and mercy. Ephesians 2:8-9 elaborates on this truth by affirming that 'it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works, so that no one can boast.' This demonstrates that the entire process of salvation—election, redemption, and ultimately glorification—is orchestrated by God’s sovereign will, independent of human effort.
