How do we know that God's grace is not based on our works?

The Bible is clear that God's grace is not contingent upon human effort or worthiness. Romans 9:11 states that the purpose of God according to election stands 'not of works, but of Him that calleth.' This emphasizes that salvation is a gift of grace, entirely initiated and sustained by God, rather than based on any actions we might take. Understanding this truth frees believers from the burden of trying to earn God's favor and affirms that it is through God's sovereign will that we are saved. Instead of depending on our works, we rest in the finished work of Christ for our justification and acceptance before God.
