If the people who built the railroads in the united states were actually interested in transporting people, they would now own the airlines. But they don't! The industrial historians tell us that the reason for this is that once the railroad companies had completed the huge task of driving the lines across the US, they lost their focus. Instead of continuing to pioneer ways of allowing free movement of people, they lost sight of the key end and focused internally on the one means to that end that they had made.
For a century or so, this was no problem because the rail road was still the best way to get around, but with the advent of the airlines the railroad companies were overtaken by a mode of transportation that was massively better. And their customers flocked to it.
Or at least most of them did. There were still a few old romantics who just loved the railroad and who continued to dress up in their finery, climb aboard, and drift along gently, talking to each other about how the railroad was the PROPER way to travel. About haw much better it was than this fancy airline stuff. They assured each other everything was going to be just fine, while the planes full of people shot by overhead.
New wine is currently being waisted by ruptured wine skins. And it outrageous to ask the workers to keep pressing the grapes when the vineyard keeps pouring it into old old skins, allowing them to rupture and spill the newness into the drains.
NOTE: This is a widely circulated parable among the emerging church movement. As far as I can tell it's author is unknown. I have heard it told several times, sometimes on podcasts sometimes in person. It has even been included in the forward to at least one book. But each time the storyteller explains they heard it from someone else... I believe this a mark of the emerging church, that we share stories and ideas freely. The ultimate goal is the healing of our world through the expansion of "The Kingdom of God."
