In a world where sin and darkness seem to be increasing all around us, Christians must ask themselves, "what makes me different?" We also need to wrestle with why we are not just called to have a private faith that never gets involved with other people's lives. When Jesus called us salt and light, He was saying that as Christians, we are supposed to make a difference in the world around us simply because of who He has made us to be through the Gospel. What does being salt and light look like? We explore that in this sermon.
