Ten Virgins are the Church

"The parable of the ten virgins is intended to represent the second coming of the Son of man, the coming of the Bridegroom to meet the bride, the church, the Lamb’s wife, in the last days; and I expect that the Saviour was about right when he said, in reference to the members of the church, that five of them were wise and five were foolish; for when the Lord of heaven comes in power and great glory to reward every man according to the deeds done in the body, if he finds one-half of those professing to be members of his church prepared for salvation, it will be as many as can be expected judging by the course that many are pursuing."
