“Shall Suddenly Come to His Temple”

Church Educational System
Notice that in 3 Nephi 24 the Savior again demonstrated the value of scripture. He supplied the Nephites with the writings of Malachi, an Old Testament prophet who lived nearly two hundred years after Lehi left Jerusalem. His teachings would not have been on the plates of brass.

One fulfillment of the prophecy found in verse 1 happened when the Lord appeared in the Kirtland Temple on 3 April 1836 (see D&C 110), but the complete fulfillment will take place as part of the Second Coming.
