If the gospel isn't good news for everybody, then it isn't good news for anybody. And this is because the most powerful things happen when the church surrenders its desire to convert people and convince them to join. It is when the church gives itself away in radical acts of service and compassion, expecting nothing in return, that the way of Jesus is most vividly put on display. To do this, the church must stop thinking about everybody primarily in categories of in or out, saved or not, believer or nonbeliever. Besides the fact that these terms are offensive to those who are the "un" and "non", they work against Jesus' teachings about how we are to treat each other. Jesus commanded us to love our neighbor, and our neighbor can be anybody. We are all created in the image of God, and we are all sacred, valuable creations of God. Everybody matters. To treat people differently based on who believes what is to fail to respect the image of God in everyone. As the book of James says, "God shows no favoritism." So we don't either.
