In the scriptures there isn't anything relating to Jesus' life on Wednesday. We know He is in Jerusalem. And we know that He taught parables while He was there. So we do the parable of the 10 virgins. It's wonderful because we have an oil lamp and can use that as a really cool visual. We talk about filling our own lamps with oil every day with prayer, scripture study, family home evening, attending church meetings and the temple, following the prophet, and many more. We want to be ready when Jesus comes again and certainly don't want to be told "I know you not". "Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh"
