Today, Jesus famously says, ‘You are the salt of the earth… you are the light of the world.’
Note that he doesn’t say ‘you should be salt…’ He says you already are. He spells out our identity before saying what he expects of us. But why salt and light? Because they are both ordinary, and that’s exactly how God’s kingdom spreads: through the small, steady and faithful action of certain things we all consider very ordinary.
So, what can we learn from salt and light?
Firstly, note that salt doesn’t change food ingredients; it simply enhances what’s already there. In the same way, Christians are meant to be a subtle presence, awakening the goodness that already exists in the people and world around them. Think of someone you know at work, at home or in your community, who just by their presence makes things better. They don’t have to give speeches or force any change; they simply and quietly bring out the best in others. This is what Jesus wants us to do: to be the pinch of salt that makes things better.
Secondly, salt has long been used to preserve food from decay. Today, there are many places where conversations, attitudes or relationships can begin to spoil; where negativity, cynicism, or injustice can start to spread. And sometimes, even without realising it, we become the ones who hold things together. We stop things from decaying. We preserve the truth. We keep things on track. This is what salt does, and what Jesus calls us to do.
Then Jesus talks about light, and light has one essential task: to be visible.
Light is a remarkable thing. It doesn’t panic when darkness approaches. It doesn’t argue with the darkness or resent it. It simply shines, and by shining, it changes the whole room. This is what Christians are called to do.
In a world that often seems dark, confused or unhappy, Christians are meant to shine with a quiet, steady goodness that points people to God. Not showy or loud, but quietly radiant, so that others see something in you that points beyond yourself.
