"Most of us have been led to believe that prophets 'foretell' the future. That is true, and it is also misleading. It is not the point here. Prophets are seers of the big patterns; they see what is always and forever true. Prophets like Isaiah know how God acts by watching and listening, and they have no doubt about the 'meta-narratives,' the Real Story that is always going on inside of our little stories. One of the big patterns is that God’s message always gets wider and more universal, despite our best attempts to limit it."
