I believe in miracles is an old book by Nancy Kuhlman. Do you know where I can find it?
There is a book by that title by Kathryn Kuhlman--is that the one you mean? Unfortunately we do not own a copy, but it should be easy to borrow from another library system via interlibrary loan--you would have to pay postage one way. You can find more information about that option here: http://www.omahalibrary.org/my-library/interlibrary-loan
Let us know if you have any questions!
