Biblical and modern prophecies give many signs of the Second Coming. These include:
The fulness of the gospel restored and preached in all the world for a witness to all nations.
False Christs and false prophets, deceiving many.
Wars and rumors of wars, with nation rising against nation.
Earthquakes in divers places.
Famine and pestilence.
An overflowing scourge, a desolating sickness covering the land.
The whole earth in commotion.
Men’s hearts failing them.
(See Matt. 24:5–15; JS—M 1:22, 28–32; D&C 45:26–33.)
In another revelation the Lord declares that some of these signs are His voice calling His people to repentance:
“Hearken, O ye nations of the earth, and hear the words of that God who made you. …
“How oft have I called upon you by the mouth of my servants, and by the ministering of angels, and by mine own voice, and by the voice of thunderings, and by the voice of lightnings, and by the voice of tempests, and by the voice of earthquakes, and great hailstorms, and by the voice of famines and pestilences of every kind, … and would have saved you with an everlasting salvation, but ye would not!” (D&C 43:23, 25).
These signs of the Second Coming are all around us and seem to be increasing in frequency and intensity. For example, the list of major earthquakes in The World Almanac and Book of Facts, 2004 shows twice as many earthquakes in the decades of the 1980s and 1990s as in the two preceding decades (pp. 189–90). It also shows further sharp increases in the first several years of this century. The list of notable floods and tidal waves and the list of hurricanes, typhoons, and blizzards worldwide show similar increases in recent years (pp. 188–89). Increases by comparison with 50 years ago can be dismissed as changes in reporting criteria, but the accelerating pattern of natural disasters in the last few decades is ominous…
“In modern revelation we have the promise that if we are prepared we need not fear (see D&C 38:30).”Preparation for the Second Coming

Why Did The Lord Send Elijah?
Henry B. Eyring, of the Quorum of the Twelve Apostles, of the Church of Jesus Christ of Latter-Day Saints discusses this question during the April 2005 General Conference which was held in SLC, Utah, USA.
It is important to know why the Lord promised to send Elijah. Elijah was a great prophet with great power given him by God. He held the greatest power God gives to His children: he held the sealing power, the power to bind on earth and have it bound in heaven. God gave it to the Apostle Peter. And the Lord kept His promise to send Elijah. Elijah came to the Prophet Joseph Smith on April 3, 1836, just after the dedication of the Kirtland Temple, the first temple built after the Restoration of the gospel. Joseph described the sacred moment.“Hearts Bound Together,” Ensign or Liahona, May 2005, 78
Eyring then quotes Joseph Smith’s account of “visions manifested to Joseph Smith the Prophet and Oliver Cowdery in the temple at Kirtland, Ohio, April 3, 1836” as recorded in Doctrine and Covenants 110. This experience describes “Elijah’s return and he commits the keys of his dispensation as promised by Malachi” (see Doctrine and Covenants 110).
13 After this vision had closed, another great and glorious vision burst upon us; for Elijah the prophet, who was taken to heaven without tasting death, stood before us, and said:Doctrine and Covenants 110:13–16
14 Behold, the time has fully come, which was spoken of by the mouth of Malachi—testifying that he [Elijah] should be sent, before the great and dreadful day of the Lord come—
15 To turn the hearts of the fathers to the children, and the children to the fathers, lest the whole earth be smitten with a curse—
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.
What did Elijah restore?
President Henry B. Eyring said: “It is important to know why the Lord promised to send Elijah. Elijah was a great prophet with great power given him by God. He held the greatest power God gives to His children: he held the sealing power, the power to bind on earth and have it bound in heaven” (“Hearts Bound Together,” Ensign or Liahona, May 2005, 78).See Come Follow Me, January 11–17

I believe the earth was created for families as taught throughout scripture (insert reference here) and as found in The Family: A Proclamation to the World. The family is sacred. Marriage is sacred. Many share different beliefs, but The Savior’s love is infinite and eternal (see D. Todd Christofferson) just as the family can be and is meant to be (insert scripture reference here). However, we all have our own agency (reference) and we must decide for ourselves the path we will follow. In the end, “Decisions determine destiny” (Thomas S. Monson).
