I love this quote from Eugene Peterson:

The churches of the Revelation show us that churches are not Victorian parlors where everything is always picked up and ready for guests. They are messy family rooms. Entering a person’s house unexpectedly, we are sometimes met with a barrage of apologies. St. John does not apologize. Things are out of order, to be sure, but that is what happens to churches that are lived in. They are not show rooms. They are living rooms, and if the persons living in them are sinners, there are going to be clothes scattered about, handprints on the woodwork, and mud on the carpet. For as long as Jesus insists on calling sinners and not the righteous to repentance – and there is no indication as yet that he has changed his policy in that regard – churches are going to be an embarrassment to the fastidious and an affront to the upright.”
