Jesus calls his followers to be the salt and light of the world. As his followers, being salt effectively preserves and enhances what is best in the society around us. We can undermine what is dysfunctional in the surrounding culture. We are also light by which people around us come to see what is worth seeing. By the quality and integrity of our lives, we shed light, illumining what is beautiful and revealing what is ugly. The clear implication is that, without vibrant Christians, the world is a much worse place. Mother Teresa of Calcutta would never have achieved much for the poor if she hadn’t lived authentic discipleship. People can see through false words and self-promotion. That is the sense of the Arab proverb: “Three things cannot be hidden: a mountain, a man riding on a camel, and love.” Mother Teresa embodied the love of Christ that all disciples are called to be.
