"And at that day, when I shall come in my glory, shall the parable be fulfilled which I spake concerning the ten virgins.
For they that are wise and have received the truth, and have taken the Holy Spirit for their guide, and have not been deceived--verily I say unto you, they shall not be hewn down and cast into the fire, but shall abide the day.
And the earth shall be given unto them for an inheritance; and they shall multiply and wax strong, and their children shall grow up without sin unto salvation."
Doctrine and Covenants 45:56-58
This is pretty cool. I like when there is follow-up on the parables, giving us additional information. (The original parable is in Matthew 25:1-13, if you want to read it.) In the original parable, the virgins were waiting for the bridegroom, and it was taking a long time, so the lamps, which only burned for a few hours without being refilled, were starting to go out. The foolish virgins asked the wise virgins to share their extra oil, and the wise virgins told them they couldn't, or else they wouldn't have enough for themselves to last until the bridegroom came. So, the foolish ones went to buy extra oil, and after they left to do that, the bridegroom came, they all went into the wedding, and the doors were shut (presumably coming late they wouldn't be allowed back inside). And here it talks about the same parable, and how if we are wise and receive the truth, and have the Holy Spirit to guide us, that we'll survive Christ's second coming. So, in relating it back to the original parable, perhaps truth and the guidance of the spirit are the oil in our lamps... so testimony and dedication to God. And those are things that you can share in a way when you share the gospel, but in another way they can't really be shared in that we can't rely on someone else's testimony when Christ comes. Everyone will have to know for him or herself.
Today, let's work on our testimonies, and our dedication to God. Let's make sure we're keeping the spirit with us as a constant companion. If we work on it now, hopefully we'll have enough oil in our lamps when the time comes. That last part about children growing up without sin unto salvation... wow. I want to live in a place like that. Let's prepare, so that we can.
