Leave it to the Catholics to stop and get the car washed when the dealer only cares about the interior...
Leave it to a Protestant to misunderstand a simple metaphor. The point is that it is not a place of judgment ("Weighing station"), but a place of cleansing ("Car wash").

Your car wash benefits you NOTHING..
Rev 7:14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
It was a joke. Get a grip.
