Why did G-d perform the miracle of Purim in a natural fashion? For the reason that G-d wanted to demonstrate to the Jewish nation and to the entire world, that everything comes from G-d, always. He wanted to teach us that not only the open miracles derive from Him, but even when things seem to be a natural event, it is really always G-d controlling the events.
