If you're using smart quotes (i.e. “ & ”), you can search for one or the other, instead of using " - which finds both. Of course, if your document has the wrong smart quotes in some locations, those will still have to be processed manually. Alternatively, you might use a Find/Replace with:
Find = ^w"^w
Replace = ^32"
Instead of ^32 you could insert a space. This will find only those double-quotes that have white space before and after - thus leaving repentance." alone.
