It is no accident that when the apostle Paul was grappling with the eternal purpose of God for humanity, he chose the word "adoption" to describe it. The basic idea of adoption is to include. It means that one who is foreign, outside the family circle, is drawn, in grace and love, within the family circle. And the purpose of that act of adoption is so that the outsider can share in the family's life. The whole mind-boggling act of creation is driven by the desire to share the great dance with us.
