Another approach on miracles:

In G.B. Shaw's "St. Joan", there's a bishop (who is one of the villains of the piece, if I remember correctly), who is speaking with some other cleric. He mentions that Joan has done a miracle. The other cleric is surprised to hear him say that, since neither of them believes that she's sent by God or angels or the Virgin. And the bishop says words pretty much like this: "A miracle is an event that creates faith."

His point being that actual divine intervention is not necessary (if it ever happens); that an event that has the appearance of divine intervention in the public eye is the miracle, whatever its cause.
