I've seen many signs in front of church buildings that read, "Come as you are," and often wondered what message they hoped to convey. I know that regardless of "how" I show up to services, God knows whether my heart is focused on Him or caught up in self.  I may come impeccably dressed while my heart is in shambles. I wear threadbare clothes while possessing a heart receptive to God's discipline. Our attire, whether stainless or shabby, might be able to create a certain impression on people, but it will not conceal from God the state of our hearts or our minds.
