How does the gospel of Christ challenge our self-righteousness?

The gospel message profoundly challenges human pride and self-righteousness as it declares that salvation is not achieved through our works but through faith in Christ alone. Romans 9:16 encapsulates this truth: 'So then, it is not of him that willeth, nor of him that runneth, but of God that showeth mercy.' The gospel insists that our righteousness is as filthy rags before God's holiness, emphasizing the need for divine grace. This radical message offends many because it strips away any grounds for boasting and calls us to humility, recognizing our utter dependence on Christ for redemption.
