the foolish virgins were the ones who went forth to meet the bridegroom TOO SOON

the wise were those who waited according to scripture and the order of the trumps and in so doing YET had oil to light their lamps when the bridegroom arrived

whereas the foolish who went out too early had already spent the oil in their lamps, hence they were empty at the Second Advent.

let those with eyes to see and ears to hear know the mystery that lies therein.
