It never ceases to amaze me when there is a counter to any sort of prophetic warning. Is it any different then the frustration the engineers who had examined the bridge that fell and warned about what needed to be done? What frustration the prophets must have had!
 
The five unwise don't understand the difference between light and dark because they choose to live in the dark. When darkness comes they can not tell. They can only quote their favorite scriptures. Lord knows they have heard the warnings in Ephesians  5 and Galations 5 and many other places but it just seems to go right past them unabsorbed. Like Mary's prophetic warnig it is a childish game of hide and seek, played by adults. It is ok to indulge is sin as long as no one sees me. That is truely living in the dark. When darkness fell they had no way to light their lamp.
