“You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot. “You are the light of the world. A town built 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 others, that they may see your good deeds and glorify your Father in heaven." Matthew 5:13-16
What does it mean to be Salt and Light? Salt is both a preservative and enhances flavor. Jesus seems to be saying that those who follow God should make the world a more enjoyable place for everyone by enhancing and sharing the goodness of God with others. As for light, Jesus is sharing that how we live our life should be like a light drawing others to God. The metaphor of salt and light is a reminder to followers of Jesus that through our faith and how we live our life, we should have an obvious impact on everyone who comes in contact with us. Jesus is asking us to not only be devoted to God, but He is asking us to have an influence on the world around us.
