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. . .

. . . Now the question is, how can we keep oil in our lamps? By keeping the commandments of God, remembering our prayers, do[ing] as we are told by the revelations of Jesus Christ, and otherwise assisting in building up Zion. When we are laboring for the kingdom of God, we will have oil in our lamps, our light will shine and we will feel the testimony of the Spirit of God. On the other hand, if we set our hearts upon the things of the world and seek for the honors of men, we shall walk in the dark and not in the light. If we do not value our priesthood, and the work of this priesthood, the building up of the kingdom of God, the rearing of temples, the redeeming of our dead, and the carrying out of the great work unto which we have been ordained by the God of Israel--if we do not feel that these things are more valuable to us than the things of the world, we will have no oil in our lamps, no light, and we shall fail to be present at the marriage supper of the Lamb.
