This phrase, which the Millerites used to describe their message to the world, is adapted from the words of Christ’s parable regarding the wise and foolish virgins who were waiting for the bridegroom to come forth that they might go “with him to the marriage.” During the long wait they “all slumbered and slept. And at midnight there was a cry made, Behold, the bridegroom comes; go you out to meet him.” The wise virgins had taken oil in their lamps. All arose when the cry went forth at midnight. The foolish went to buy Oil; the wise went in with the bridegroom to the marriage celebration, and “the door was shut.” The lesson Christ drew was this: “Watch therefore, for you know neither the day nor the hour wherein the Son of man comes.” Matthew 25:1-13. The language of this parable is woven all through Millerite literature. They believed they fulfilled this parable.
The subject of the Sanctuary and the investigative judgement should be clearly understood by the people of God. All need a knowledge for themselves of the position and work of their great High Priest. Otherwise, it will be impossible for them to exercise the faith which is essential at this time, or to occupy the position which God designs them to fill. . . . The Sanctuary in heaven is the very centre of Christ’s work in behalf of men. It concerns every soul living upon the earth. It opens to view the plan of redemption, bringing us down to the very close of time, and revealing the triumphant issue of the contest between righteousness and sin. It is of the utmost importance that all should thoroughly investigate these subjects, and be able to give an answer to everyone that asketh them a reason of the hope that is in them” (GC 488, 489).
