I hope that this has not been discussed to death already, but on re-
reading the book I was struck by Dumbledore's mention to Harry of the 
locked room in the Department of Mysteries that "contains a force 
that is at once more wonderful and more terrible than death, than 
human intelligence, than forces of nature...It is the power held 
within that room that you possess in such quantities and which Lord 
Voldemort has not at all."  
Presumably he means the power of love.  It also seems as though that 
is the same locked room that melted Sirius's knifeblade when Harry 
tried to open the door. I wonder if that room will play a role in the 
next two books.
