"Here is the inescapable truth: If we want to follow God's will -- if we want to fall in line with the story of biblical history, if we truly want to be followers of Jesus in the world -- then we need to understand God's sending -- and respond to it. But don't miss this key element in that statement: It's God's mission. We derive our mission from the missio Dei. We don't go because Bono or Bill Gates are going. We don't go because the planet is in peril. We don't even go because we want to help people. Of course we want to help, and we don't want to turn away when we recognize wrong that need to be righted, but those aren't the main things. We go because we are joining God in His mission."
