" Think of the many, many stories about God choosing people. There are Moses, Abraham, and Sarah; there are David, Jeremiah, Gideon, Samuel, Jonah, and Isaiah. There is Israel itself. Much later there are Peter and Paul, and, most especially, Mary.
God is always choosing people. First impressions aside, God is not primarily choosing them for a role or a task, although it might appear that way. God is really choosing them to be God’s self in this world, each in a unique situation. If they allow themselves to experience being chosen, being a beloved, being somehow God’s presence in the world, they invariably communicate that same chosenness to others. And thus the Mystery passes on from age to age. Yes, we do have roles and tasks in this world, but finally they are all the same—to uniquely be divine love in a way that no one else can or will. "
