Missional living means living the love of God in a way that impacts other people. As Paul said, we have been reconciled to God, and we are now to serve others with the goal of seeing them reconciled as well. This reconciliation affects all aspects of our lives, beginning with our relationship with God, but also affecting our relationship with other people.
However, the common grace of God and our common reconciliation with God does not mean that we all serve others in the same way. God has gifted us differently. He has given us different talents. We all have different opportunities. God has given us different passions and interests. Thus, we will serve others in different ways. There is a danger, especially among leaders, in thinking that every Christian will serve in the same way that I (or the leader) serves. This is not the way that God works.
Thus, missional living will look different for different people. However, in all instances, a life that mirrors the mission of God will live the love of God in the lives of others in order to reconcile them to God and to one another.
