our duty (Brigham Young)

I have frequently thought upon the preparation that is necessary. Suppose the word should come, “Return and build up the center Stake of Zion,” are we ready for it? No. I have often alluded to our mechanics. We have not a mechanic that would know how to lay the first stone for the foundation of the wall around the New Jerusalem, to say nothing about the temples of our God. Are you prepared for the day of vengeance to come, when the Lord will consume the wicked by the brightness of his coming? No. Then do not be too anxious for the Lord to hasten his work. Let our anxiety be centered upon, this one thing, the sanctification of our own hearts, the purifying of our own affections, the preparing of ourselves for the approach of the events that are hastening upon us. This should be our concern, this should be our study, this should be our daily prayer, and not to be in a hurry to see the overthrow of the wicked. Be careful; for if they were all to be overthrown at once, how many would there be left that are called Saints? Not as many as I would have remain. We are prepared for the day that is approaching: let us then prepare ourselves for the presence of our Master—for the coming of the Son of Man. The wicked and the ungodly are preparing for their own utter overthrow, and the nation in which we live is doing so as fast as the wheels of time can roll, and ere long sudden destruction will come upon them. Seek not to hasten it, but be satisfied to let the Lord have his own time and way, and be patient. Seek to have the Spirit of Christ, that we may wait patiently the time of the Lord, and prepare ourselves for the times that are coming. This is our duty.
