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.
Someone out there is on their knees, worn out with suffering. It might even be you.
