What does the Bible say about God's grace and our sin?

The Bible, particularly in Isaiah 64:6, emphasizes that even our best efforts and righteousness are tainted by sin, described as 'filthy rags.' This stark reality drives us to recognize our utter dependence on God's grace for salvation. The depth of our sinfulness reminds us that no one can stand before a holy God without the covering of grace. We are taught to come before God in humility, confessing our sinfulness and pleading for His mercy, acknowledging that our only hope lies not in our own works but in the finished work of Christ.
