God’s Dreadful Day is at Your Door 

D&C 110:16; “Therefore, the keys of this dispensation are committed into your hands; and by this ye may know that the great and dreadful day of the Lord is near, even at the doors.”

Vision of Smith & Cowdery in Kirtland, OH on April 3, 1836. History of the Church 2:435-436. 

The “eyes of understanding were opened” to these two men when they saw the great and dreadful day of the Lord being near.  If the Lord was at the door it’s been a long wait for him – 176 years at the time of this writing in 2012.
