“You are the light of the world. A town built on a hill cannot be hidden. In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.”
This passage from the Sermon on the mount is rather famous. It is part of a number of instructions to how his disciples should behave. Here, he is calling his disciples to be examples to the rest of the world, that their good deeds may encourage others to glorify God. In the Tyndale commentary, he writes,
But the disciples of Christ must not, through fear of being an unworthy influence, remain silent about their religion. They can, and they must, bear witness to the faith that is in them through personal example. This is the truth underlying the metaphor used by Jesus when He tells them they are the light of the world.
So the disciples must not hide themselves, but live and work in places where their influence may be felt, and the light that is in them be most fully manifested to others – not for their own glorification, but that others may see that the light of real Christian goodness, finding expression in practical acts of loving-kindness and service, is a light not of this world but coming from God, and may in consequence be led to give honour and praise to its Giver
What sort of things do you do to let your light shine?
