Gino,
 
I went back and reread your question.  I think the best answer I can give is that the 2 passages (Matthew 25 and Luke 12) are so similar in nature that it seems logical to identify the foolish virgins as the waiting servants.
 
The foolish virgins wanted to go with the groom, but were excluded at His first appearance.  When He comes back from the wedding they are found ready the second time.
 
When you look at the entire study titled The Two Feet of the Body of Christ, you'll see a number of comparisons that taken as a whole (including bible references) will support my hypothesis.  You can search for my study here on the Five Doves website.  If you have any difficulty, I'll send it if you'd like.
 
I hope my response wasn't too circular and that a little bit of help was provided.
