The principle that you must buy the oil for yourself and not depend on someone else to provide it can apply to all Christians and until the Midnight cry that is a valuable way to expound this parable. But bridesmaids are servants of the Bride, they are not the bride. The lamp is the word of God, so a lit lamp is someone ministering the word of God in the dark night to shine the way. Believers have two statuses, one is the bride of Christ, but the other is that they are servants of the Lord. So it is reasonable to look at these ten as a complete number of "servants of the Lord". But they have a very specific function, to watch for the Lord's return. This parable is telling us that many of those who were very keen to watch for the Lord's return, especially after Israel returned to the land, they have fallen asleep. Not all, the complete number would be 12. So 10 out of 12 fell asleep and are woken up by the Midnight cry. So this is telling you that prior to the Day of the Lord starting there will be a 9 year period, where the number of those declaring the Day of the Lord is about to start and pointing to prophecies from the Bible being fulfilled will increase greatly. Before you had "prophecy watchers" and "prophecy club" but during this period interest in prophecy will increase greatly. However, half of the lamps will go out because they are like those seeds sown in rocky places without much root.Tell me who they are in your superior interpretation.
The "Ten Virgins" refer to Ten Feast of Trumpets spanning a nine year period from 2017 to 2026. The Midnight Cry is the Great sign in Revelation 12 and the manchild is prefigured by Josiah who is made king when he is 8. Feast of Trumpets in 2017 was September 20-22, Feast of Trumpets in 2026 is September 11-13, so even though it has been "nine years" the manchild born in 2017 is still 8 years old on September 11, 2026.
