Jesus told his disciples in Matthew 5:14–16:
You are the light of the world. A city seated on a mountain cannot be hid. Neither do men light a candle and put it under a bushel, but upon a candlestick, that it may shine to all that are in the house. So let your light shine before men, that they may see your good works, and glorify your Father who is in heaven.
But what does it mean to be the light of the world? The Peace Prayer of St. Francis tells us what it means to be the light of the world.
The Peace Prayer of St. Francis, although attributed to St. Francis of Assisi, was written by an anonymous French writer. This beautiful prayer first appeared in France in 1912. Here is my version of the prayer:
Lord, make me an instrument of Your peace;
Where there is hatred, let me bring love;
Where there is offence, let me bring pardon;
Where there is discord, let me bring harmony;
Where there is error, let me bring truth;
Where there is doubt, let me bring faith;
Where there is despair, let me bring hope;
Where there is darkness, let me bring light;
Where there is sadness, let me bring joy.
O Master, grant that I may not so much seek
To be consoled as to console;
To be understood as to understand;
To be loved as to love.
For it is in giving that we receive,
For it is in forgetting that we find,
For it is in pardoning that we are pardoned,
For it is in dying that we are reborn to eternal life.
