variety: Matthew 5v14-16

14 ‘You are the light of the world. A town built on a hill cannot be hidden. 15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. 16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.

Life is necessary for life. Without light, we have no plants, no warmth, no beacons. 

Darkness, as the Gospel of John puts it, seeks to overcome the light (John 1:5). “This little light of mine” can shine, but it can also be snuffed out. Thus light is a precious commodity that must be preserved. 

Too much light however can blind. Effective light does not call attention to itself; rather, it lights up the world….  

For the disciples, Jesus is the light of the world. Yet as he states in John 9:5, he is the light “as long as I am in the world.” The disciples therefore take up his role: acting as he instructs them.… They too can be the light of the world…. 

Once the disciples recognize that they are light, they also recognize that their role is to shine so that others can find their way. Jesus knows that light can be hoarded and fail to fulfill its proper function. He states first the obvious: “A city built on a hill cannot be hid” (Matthew 5:14). His followers are to become like that city: a refuge, a home, a place where there is salt and light, love and compassion….   

That light cannot be restricted to any church building or community, as the city metaphor indicates. To be the light of the world is to shine … in any place where there is loneliness or despair, sickness or pain. Even in times and places, still today, when the church has had literally to go underground, it cannot be hid since it is known for its good deeds.
