Luke 11:34 Your eye is the lamp of your body. When your eyes are good, your whole body also is full of light. But when they are bad, your body also is full of darkness. (NIV1984)
Light is produced when electrons in atoms get extra energy and jump into a higher energy level than they normally belong but due to the pull of the nucleus it comes back to its normal level. When it drops back it has to give up the extra energy and it is lost as an electromagnetic wave. Different elements will produce their own special color of light/EM wave; this is one-way chemists know what is in a sample they are testing. The Greek word here for light is related to our word phosphorous and photo.
We are like those electrons when we take God’s energy and “jump” out of our comfort zone; we light the world up. Since everyone in the Body of Christ is not the same (element) our “lights” will look different. Another great picture here is that God will pull you back where you belong to get you ready for the “next time.”
If “eyes as lamps” makes you think of super-heroes with glowing eyes I don’t think you are alone. (see Light #2 on eyes) I have taught this verse before, as to how you look at things make a difference; like you always finding the positive or negative in something. But lamps light things up and since your body is what is full of light we need to reverse that idea. What we choose to look at and put in front of our eyes is “fueling” our lamps and that is what fills us with light.
Father, help us fuel our lamps with your fuel so we can go light up your world.
