We are called to be a city on a hill not a city behind a hill. In many ways things haver changed regarding the culture and it can be hard to stand firm and shine bright in a world that is looking to put the light out. Throughout history God has chosen people to stand and to represent the truth and the light to a dark and lost world.
Our time is no different. The gospel is the most positive thing to have touched this planet. If we believe that, it should compel us, and drive us to show the love of the gospel.
