How do you pray for a miracle?

“Don’t give up before the miracle happens.”  (Fannie Flagg)  I recently read Zealot, a best-seller about Jesus, the person.  It references other miracle workers in biblical times, comparing them to Jesus.  What do we pray for when we pray for a miracle?  I simply want God to know my feelings and to work his “will.”  Sometimes the “miracle” happens in a totally unexpected way.  Are you looking for a particular miracle?    ;-)  Jack
