The analogy goes so far, and then we can see no more. Were the unwatchful virgins called upon later for some other reason? The story doesn't go past the big event of the coming of the bridegroom, who states he never knew them. Wiser souls than I can debate such details. I know I would not want to miss the second coming even if other chances follow.
I have heard that the entry of the wise virgins might only temporarily exclude the unwise. Others see the unwise as not possessed of a true faith; therefore, not really Christian to begin with.
