In this sermon, we talk about what role Christians should serve in society.  We discover two extremes we should avoid: withdrawing from the world and losing sight of the central issue, the gospel.  Being salt and light in our society requires us to address societal issues, and we learn that we should prioritize certain social issues because they are strongly connected to the gospel.  We address the sanctity of all human life, sexual immorality, helping the helpless, and war.
