And somehow, the virgins who have no oil are excluded. A caution worth listening to.
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.
It wasn't that they had no oil, it was that they went to sleep and let the lamps go out.
