The foolish 'took no oil with them'.
No oil at all. The common misinterpretation of this parable suggests that the foolish took no extra oil. But the text says 'they took no oil'.
No oil at all.
The foolish took 'their lamps'. Again the common misinterpretation supposes that there was oil in the lamps but no 'vessel' containing extra oil. But the text does not suggest that. The text says . . . . 'they took no oil'.
All they had was a lamp.
This was the depth of their folly : a lamp, a wick, a means of lighting the wick . . . but no oil.
The wise had oil in their vessels, that is to say the 'vessel' that is a part of every oil lamp. It is part of the lamp.
The foolish had an empty vessel. The vessel, part of the lamp, was empty.
They were so foolish that they did not know that you need oil in order to light a lamp.
So when the cry came, all lit the wicks on the ten lamps. Five wicks sputtered and died. The wick went charcoal black. A wick just burns up if there is no oil present.
They ... had ... no ... oil.
That is how foolish they were. They did not understand how a lamp works.
Having the gospel without the Holy Spirit within oneself is like having a lamp without any oil in the belly of the lamp, in the 'vessel' of the lamp.
One has just a piece of apparatus.
But no life. No oil. No burning presence. No Spirit.
And a piece of metal apparatus (bare doctrine, mere words, letters on a page, verbals in the mouth, doctrines in the head) will just not do when the Bridegroom appears to consummate the marriage.
The Presence of the Bridegroom was already known by the wise. For they had the oil, already. They had an anointing. They were full of the Holy Spirit.
This cannot be 'shared'. One must possess it, oneself.
One can share fellowship, one can share truth, one can share one's own experiences, one can share teaching. But one cannot share the presence of the Holy Spirit with another. If both have that, then there is a bond : 'we all drink into one Spirit', 1 Corinthians 12:13.
But ye have an anointing from the Holy One [1 John 2:20 YLT]
This is experienced as a result of a baptism of repentance. Many talk of 'the baptism of the spirit' but few seem to experience a baptism of repentance, leading to genuine faith in the Lord Jesus Christ.
Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: [1 Peter 1:22 KJV]
Obeying the truth through the Spirit results in unfeigned love of the brethren.
That genuine charity will share what it can. But it will also possess, for itself, that which is personal and intimate and essential to life.
And it will be ready when the Bridegroom appears.
