There are times in our Christian walk where we think we've got it all figured out but, our righteousness is of filthy rags. Once we think we've got it figured out, that is when we are about to fall. So at the best that we could do, our works are as filthy rags compared to Gods glory. We all fall short daily and must repent before God. When you get into a hopeless condition with sin, just call on Jesus. Being in sin is truly a hopeless condition. If your saved you can not walk in sin. You might be able to walk in it for awhile but God will not dwell with sin therefore you will walk further and further from Him. A good potter will start out with a lump of unformed clay beginning to work it until it's something that both the potter and others would be proud of. If we were the potter we would just get rid of the lump of clay instead of making it better. At the root of being prepared and ready for church is getting the imperfections out, the sins that are in our lives.
