Here’s my two cents.
Jesus tells us we are salt and light but really doesn’t tell us what he means. What he does do is warn us not to fake being salt and not to hide our lights.
Because, if we are connected to him, we are both and it isn’t clear what this means, it causes us to compare and contrast the two. How are salt and light the same? What do they have in common? And how are they different from each other?
And once we ponder this awhile, a few observations rise to the surface and might prove helpful.
Salt describes our substance, what is inside us.
Light describes our essence, what emits from us.
Salt is transportable. You can carry it in a sack and take it from one place to another. It describes the body we live in and operate out of.
Light is transmissible. It shines from a source and is seen across distances. As salt describes our life here on earth, light describes our life emanating out of heaven. It is centered and burning from within us. It is God shining through.
As salt is finite, light is as close to infinite as my mind can comprehend.
Salt is about what I can do right here, right now. It is about making this world a better place. Light is about life’s meaning, mine and yours, in a context beyond the confines of planet earth.
Those are some of my thoughts. What do you think?
Oh, and here is another. Both exist without noise. We aren’t to be waterfalls or volcanoes of the world. But we are necessary, vital even, and do communicate important messages when living as he wants us to.
Scripture tells us that the people who walked in darkness have seen a great light, Jesus. He left believers the Holy Spirit, which becomes His light in us when we let Him shine.
