Filthy rags in the Bible: Isaiah 64:6
When we do something good, we're proud of what we've done, but this passage says that even our best, most noble works are like "dirty rags" when it comes to earning us a place in heaven--they're useless and good for nothing. They're certainly not enough to bring us into a right relationship with God--for that, we need Christ.
