Who symbolizes groom in the parable of 'ten virgins

In the Bible, the image of a wedding is used to portray the coming of the Lord (see Isaiah 62:5; Matthew 22:1–14). Jewish weddings included the announcement of the bridegroom’s coming to the bride’s house. The weddings usually began in the evening, with the lamps lit at dusk. So midnight was later than the ten virgins would have expected the bridegroom—and the announcement came suddenly.

We do not know the timing of Christ’s Second Coming, but we should prepare for it as though it could come at any time—whether soon or late.
