As I understand it, entropy is a mesure of randomness in a system. Because 
for one ordered state there are zillions of disordered ones, in nearly all 
cases one maximum disordered state evolves into another maximum disordered 
state. Only one time in a zillion years you can expect a "miracle", that it a 
spontaneous entropy reduction. For all macroscopic systems, the Universe is 
simply too young for giving any chance to such a miracle to happen somewhere.

There is another problem, the maximum disorder contains the maximum 
information, there is no regularity giving room for data compression. So 
"miracles" would have to erase informations, something very difficult on 
quantum systems. Information can readilly be scrambled, by destroy it raise 
serious problems. So there may be no closed systems in the universe, not even 
the universe itself, so there would be no bottom line for entropy and no 
miracles.
