What is the meaning of the light of the world?

You are the light of the world, a city located on the mountain can not be hidden. Moreover, people do not turn on a lamp and put it under a bushel, but IN THE lampstand so that enlightens all men in the house. Let your light so shine before men that they may see the good deeds and glorify our Father in heaven. In light of the world we must know what we are doing in the middle of "hurricane" as Eagles, he was just "spread wings" and fly high. Position of the Light is always on top, for what "put" position light below, there is no point. "Source of Light"itself was in very high places, by that because we have to go to the top in order to become brighter and reflect the "lower ranks" in the bottom. Shaloom
