Consider the call of Christ to us all as recorded by Matthew:
You are the light of the world. A city on a hill cannot be hidden. 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. In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heave.
Jesus is saying, “You have been lit by my grace, now go let my character shine through you.” How do you do this? Jesus makes it very clear: through a public life characterised by good deeds. Here again is a call to step out into this darkened world, not succumbing to thoughts of your smallness, or the magnitude of the problem, or the distance it is from your front door. It is a call to remember who you are (someone who has been lit by the transforming grace of God) and who he is (a God of awesome power and grace) and step out to look for opportunities to light what has been dark through actions of love, mercy, justice, reconciliation, peace, and compassion.
