How do we know grace is unearned?

The core of grace in the Christian faith is that it is unmerited favor from God. This means it cannot be earned or deserved; if it could, it would no longer be grace. Romans 3:24 emphasizes that we are justified freely by His grace, indicating that our salvation and standing before God come purely from His initiative, not our efforts. Understanding this truth brings immense comfort to believers who falter and feel inadequate because it reassures them that their acceptance by God is based on what Christ has done, not on their own performance.
