And the foolish said unto the wise, Give us of your oil; for our lamps are gone out. But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.  (Matthew 25:8-9)

This is the story of the parable of the Ten Virgins

Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. And five of them were wise, and five were foolish. They that were foolish took their lamps, and took no oil with them: But the wise took oil in their vessels with their lamps. While the bridegroom tarried, they all slumbered and slept. And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps. (Matthew 25:1-7)

And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut. (Matthew 25:10)

Afterward came also the other virgins, saying, Lord, Lord, open to us. (Matthew 25:11)

But he answered and said, Verily I say unto you, I know you not.
(Matthew 25:12)

Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh. (Matthew 25:13)

Oil is representative of the infilling of the Holy Spirit.  Have you been baptized with the Holy Spirit.  This is something that should be sought out.  My books explain this.  Pray and ask for the infilling of the Spirit.  We are made to be vessels of our spirit and the Holy Spirit of God.  Are you ready for the invitation of the bridegroom Jesus for the Rapture to join Him in Heaven.
