Peace in the church by approaching those we disagree with in love and humility. Peace with the world by making evident our gentleness. Peace in prayer, bringing all our requests to God. Peace through practice.
Jesus, with all that he had, humbled himself to serve the world and reconcile it to God. In the same way, we are to be active in serving, passive in self-promoting, allowing the gospel to show it's fruit in our lives.
Paul urges the Philippians to sit loosely in their culture and live according to the gospel alone. We are called on to be bold for Christ but humble toward the world.
