All of the 10 virgins in the bible were pure and faithful to be married, but the 5 virgins were only wise and prudent, However, 5 of them weren’t vigilant or valiant in their actions. They were pure but not fully ready. Actually, they did have oil in their lamps, but not in the vessels they carried with them, and which provided reserves of oil. They lacked those reserves.
The lesson is preparedness through vision and foresight. Because it is an internal state, preparedness cannot be transferred. It is a matter of the heart, an intangible that accrues by spending long periods of time under many circumstances with the Dispenser.
What cannot be transferred to those who are unprepared are matters of attitude, character, skill, knowledge, understanding, and wisdom. They are personal attributes that are built and honed over months and years like in the lives of Joseph, David , Daniel , Esther and Paul .
So, plan ahead and be ready when the time comes. Purity is not enough, we need to be prudent too.
