Elder Dallin H. Oaks explained the meaning and purpose of the gathering:
“Another sign of the times is the gathering of the faithful (see D&C 133:4). In the early years of this last dispensation, a gathering to Zion involved various locations in the United States: to Kirtland, to Missouri, to Nauvoo, and to the tops of the mountains. Always these were gatherings to prospective temples.
“With the creation of stakes and the construction of temples in most nations with sizable populations of the faithful, the current commandment is not to gather to one place but to gather in stakes in our own homelands. There the faithful can enjoy the full blessings of eternity in a house of the Lord. There, in their own homelands, they can obey the Lord’s command to enlarge the borders of His people and strengthen her stakes (see D&C 101:21; 133:9, 14). In this way the stakes of Zion are ‘for a defense, and for a refuge from the storm, and from wrath when it shall be poured out without mixture upon the whole earth’ (D&C 115:6)” (in Conference Report, Apr. 2004, 6; or Ensign, May 2004, 8).
