The cultural background of this parable concerns Jewish wedding customs of the 1st century Palestine.
Jewish weddings had 2 phases.
The bridegroom accompanied by his friends went 1st to the brides home to obtain his bride and observe religious ceremonies.
Then he would take his bride to his own home for a resumption of the festivities.
It was on this return journey that the virgins, the friends of the bride [they are not the bride] are suppose to join the procession and enter with her into the bridegrooms house, where, in accordance with Jewish custom, the wedding feast was held.
So these virgins represents none else than a Jewish remnant (Rev.14:1-5)
They are represented by the 10 virgins [10 representing completeness] split into half [5 representing incompleteness] which correspond to the 144 000 Jewish converts.These stands in a special relation to the Lamb.They are virgins (Rev.14:4)
But of course its impossible that only 144 000 will be saved from the Tribulation period.
There are great numbers to get into heaven besides these 144 000, which is from every tongue & nation, but the 144 000 is pure Jew, not mixed.
Just because oil represents the Spirit or wisdom does not mean that for everything we should interpret it as the Spirit now.
By Christ's 1st coming, the Jews misses being part of the bride, because they failed to recognise Him as their Messiah, so they were not ready and thus broken off the olive tree.
In the Tribulation period is it just a remnant Jews that will recognise Him as their Messiah and be re=rooted into the olive tree.
Just as the Jews is slumbering now they will be slumbering during the Tribulation period in recognizing the Messiah, but only those of a ready acceptant heart, enlightened in the Word will make it.
Remember the 5 foolish didn't make it because they were not in their position, wandering off, dislocated, just as those Jewish Pharisees misled the Jews by their false doctrine in the time of Christ, also just as Adam & Eve were not to be found in their position when God was doing visitation on them.
It is wrong to interpret every prediction of Christ, every parable as pertaining to the Church.
Even the Dry Bones of Ezekiel is teached as the Church.
We can preach [comparing spiritual things with spiritual], as the Church yes, but when we teach, we need to be 100% on the dot as to its real significance.
When Scripture needs to be taken literal, we shouldn't spiritualise it. When it is to be interpreted spiritually, we shouldn't take it to be literal.
