The miracles in fact are a retelling in small letters of the very same story which is written across the whole world in letters too large for some of us to see. Of that larger script part is already visible, part is still unsolved. In other words, some of the miracles do locally what God has already done universally: others do locally what He has not yet done, but will do. In that sense, and from our human point of view, some are reminders and others prophecies.
