Why is the message of free grace important for Christians?

The message of free grace holds paramount importance for Christians because it affirms the nature of our salvation as entirely reliant on God's mercy rather than human effort or decision. This is in alignment with Romans 9:16, which states, 'It is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.' Recognizing that our salvation is a result of divine grace preserves the gospel's integrity, ensuring that all glory is ascribed to God alone and not to individual choice. Furthermore, it provides assurance to believers that their standing before God is secure, rooted in His unchanging promises and not on their fickle performances.
