Of course, how could I have forgotten the sparrows of the Bible? It so happens I have two that I got absolutely free, so I would say I saved a penny (technically an as, the Roman coin of lowest value), except the people Matthew was referring to bought those sparrows to sacrifice them and so did not spend the money I have spent on seed and egg food and a cuttlebone for them to whet their beaks on.
I like this verse not just because it is about the value of life but because it demonstrates what I think is too often overlooked, that being Jesus's sense of humor. I used the New International Version translation here, which goes like this: "Are not two sparrows sold for a penny? Yet not one of them will fall to the ground outside your Father's care. And even the very hairs of your head are all numbered. So don't be afraid; you are worth more than many sparrows." See, to me that's funny. "You guys are worth, like, a SHIT-TON of sparrows!"
(Renfield of Dracula also liked sparrows very much, of course, and being that to him Dracula was a kind of evil Christ figure I can well imagine that this verse was in Bram Stoker's mind. His eye is on the sparrow and he wants you to CRAM THE SPARROW IN YOUR MOUTH AND EAT IT.)
My sparrows are working hard on their fluttering. They like the shower rod in my bathroom and congregate at one end in their flock of two. I'm happy to report that as of Thursday the cock is totally self-feeding, which means that in a couple of days, once they really have this flying thing down, they can go. A nicer way of giving them back to God than sacrificing them at an altar, I think.
