In this text Jesus makes a truly astounding claim. He contends that Christians, those who have heard the good news and in whom the gospel has taken root, are the most useful things in this lost and broken world. Both salt and light were vitally important commodities in the ancient world and likewise are followers of Christ in the world today. By living out the beatitudes in our daily lives - these qualities of the gospelized - we have a preserving effect on a decaying culture and shed light into the lives of men and women lost in darkness. Jesus has created us for a grand purpose - to be most useful in this world today.
