An open miracle is somewhat of a disappointment for G‑d.
Once all is said and done, He got His way only by ignoring the norms of this world He created—by breaking His own rules. If He can only perform miracles by bullying Nature, He may as well concede that our world is a place where He does not belong.
So He also makes another sort of miracle—the sort that blends seamlessly into the order of things below. These are impossible miracles: They break no rules, but change everything.
In truth, they are the most awesome of miracles—these that reveal the Infinite unrestrained within the finite nature of everyday things.

The word miracle is misunderstood. it is not like the Egyptians copying what Moshe Rabbeinu did ! It is rather the everyday living that is in itself a wonder; the Mode Ani we say is recognizing our gratefulness. It seems a natural to wake up. the order of things, but if we should think twice : it is miracle! Every aspect of our our lives is imbued with the same sense of naturalness versus a miracle, and we then tend to forget that both concepts are intertwined. Why? I would like to respond that H' desired we live our lives in a most natural way, yet, not taking the peace and calm for granted. That is why we have every step of the way reminders via brachot, and Tfilot hinting that the source of all this goodness comes from H'. Living the miracles, as if they were just natural is embedded in the notion of creation. H's presence is quiet, gentle, almost unnoticeable as if we don't want to recognize that life itself IS a granted miracle for which we must be grateful.
