"Foolish, no oil, Jesus did not know them" is descriptive of the unsaved. Period. Just as "I never knew you, workers of iniquity" is also descriptive of the unsaved (Matthew 7:23). I didn't change anything. It is what it is. Deal with it.
Let's look at the parable from the beginning.
Matthew 25:1Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.
Not sure how verse 1 can be attributed to the unsaved at all.
[SUP]2 [/SUP]And five of them were wise, and five were foolish.[SUP]3 [/SUP]They that were foolish took their lamps, and took no oil with them:[SUP]4 [/SUP]But the wise took oil in their vessels with their lamps.
Now one can say that the foolish are those that believed they have no oil for their lamps when they went out to meet the Bridegroom, because they believe they need a continual filling of that oil, thus they did not have the oil by faith.
[SUP]5 [/SUP]While the bridegroom tarried, they all slumbered and slept.[SUP]6 [/SUP]And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him.[SUP]7 [/SUP]Then all those virgins arose, and trimmed their lamps.[SUP]8 [/SUP]And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.[SUP]9 [/SUP]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.
Now here are the foolish virgins waiting for the Bridegroom and nonbelievers would not be waiting for Him like that.
[SUP]10 [/SUP]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.
Virgins waiting to be received to the marriage and thus the marriage supper suggests saved believers abiding in Him knowing they are filled and ready to go always whereas the foolish ones are saved believers but denied Him as in them and thus not having faith for that oil being in them for why they are out at the market when the Bridegroom had come.
[SUP]11 [/SUP]Afterward came also the other virgins, saying, Lord, Lord, open to us.[SUP]12 [/SUP]But he answered and said, Verily I say unto you, I know you not.[SUP]13 [/SUP]Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.
Believers forget that works of iniquity that denies Him ( Titus 1:15-16 ), they will be denied; 2 Timothy 2:12 But even if they had their faith overthrown or they do not believe in Him any more, He still abides in them ( 2 Timothy 2:13 ) which was why they were still called virgins even though they were the foolish ones.
The elect are the prudent ones that are ready to go as filled believers whereas, the saved but yet denying themselves as always filled believers since they were saved are out at the market seeking to be filled when the Bridegroom had come.
If your only proof that they were unsaved believers because Jesus knew them not; then explain 2 Timothy 2:12-13 where Jesus still abides even in those that deny Him. ( Course, they are still denied, but that is what they get for not being ready to go when they are out to the market seeking to be filled with that oil where there is no end to be ready by.
