Sabbath: Shining as Lights in the Night — 1 Comment

  1. One of the major changes I have seen in my lifetime is the switch from incandescent to LED lighting. LED lighting is cheaper, and more efficient by far. Most of us have switched from incandescent lights to LEDs in our houses, and I think most new cars also use LEDs. I particularly like LED head-band torches when I am camping. They are bright and leave both hands free.

    One interesting thing about LED lights is that they can be switched on and off so fast they are used to transmit data. In fact, the world’s high-speed communication is based on LED lasers shining their lights down ultra-thin optical fibres. A few years ago they replaced the copper phone wires to our house with fibre and a little LED laser in a box. Our communication is much more reliable now.

    I have seen a proposal and demonstration in a TED talk, where they demonstrated LED car lights communicating between vehicles intelligently, avoiding collisions and solving traffic flow problems. It would make cars truly driverless. That is not like the current so-called driverless cars that use passive detectors to locate other vehicles.

    I have often thought about the parables Jesus used about candles and lights, 2000 years ago, and have imagined what Jesus would have implied if he had LEDs in mind.

    Jesus said:

    Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. Matt 5:16 KJV

    Just think of the implications of LED lights that not only shine but communicate with one another collaboratively. Could that be a model for a Christian community powered by Christ-centred love?
