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 events that are hastening upon us. This should be our concern, this should be our study, this should be our daily prayer...Seek to have the Spirit of Christ, that we may wait patiently for the time of the Lord, and prepare ourselves for the times that are coming. This is our duty.
Brigham Young, Journal of Discourses 9:3
