“Ye be [the] light of the world; a city set on an hill may not be hid; So shine your light before men, that they see your good works, and glorify your Father that is in heavens.”
A most simple analogy – think of the world as a dark room with no windows. Inside this darkness, various Christians function as matches, candles, pen lights, oil lamps, electric lamps, street lights, traffic lights, flood lights, spot lights, lighthouses, stars, nebula.
Whatever our manifestation of Light, we always outshine Dark. The questions are: to what extent? and for how long?
