How do we know we are saved by grace alone?

The doctrine of salvation by grace alone is a cornerstone of Reformed theology. In Romans 3:20-24, Paul states that no one can be justified by the deeds of the law, but rather that righteousness comes through faith in Jesus Christ. This demonstrates that our salvation is not dependent on our works but is a gift from God, which we receive through faith. The assurance of our salvation lies not in our actions but in recognizing that it is God who calls us and gives us faith, reinforcing the belief that salvation is entirely an act of God's sovereign grace.
