“All of us have become like one who is unclean, and all our righteous acts are like filthy rags; we all shrivel up like a leaf, and like the wind our sins sweep us away.” (Isaiah 64:6)

In the sight of God, even our best deeds are like filthy rags compared to the awesome purity of his holiness. His holiness is like a consuming fire that burns up all impurity in an instant.

So there is nothing we can do on our own to earn salvation
