Not meaning to "strain at a gnat and swallow a camel," as Jesus put it, but again I find myself amused at the misuse of biblical concepts because of general ignorance about the subject.
Birds have been dropping from the skies in Arkansas and Louisiana, and now we learn that in far away Sweden a hundred jackdaw birds were found in the road, dead. It is being referred to by some news sources as a bird apocalypse.
Actually, the Greek word apocalypse means an unveiling or revealing of something previously hidden. That is why the last book of the Bible is called the Revelation. Therein is John's story of an angel that came to him to reveal, to show him things that "must shortly come to pass." Among these things were the second coming of Jesus, the passing away of this world, the ushering in of a new Heaven and New Earth, the resurrection and judgment of the dead, in short, the ushering in of the Kingdom of God, which was the subject of the gospel that Jesus preached.
This bird thing might have been the end of the world for these birds, but hardly the subject of the biblical book of Revelation. This is no part of the scenario laid out in the biblical apocalypse.
A couple of my apocalyptic minded friends what asked me what this bird thing means. "Surely it must mean something." I'm sure when the facts are all in we will find a very earthly rather than heavenly meaning for it all. There's no need to worry about an imminent ending of the world.
It's interesting, but astounding to most Christians I talk to about it, that Jesus, his disciples, the author of the book of Revelation all expected the end of the world to come two millennia ago. None gave a hint they thought these events would be in the far off future. When Jesus gave his great discourse about the end of the age and accompanying events, he said, "this generation shall not pass away til all these things be fulfilled" (Matt. 24:34).
So let us live and make the most of the day we have. No one knows when or how the world will end. And these weird "Fortean" things happen. But if you look into nature, you will eventually find the explanation.
