D&C 29

 Two things I wanted to note this morning concerning the Second Coming.  The first - 

"And again, verily, verily, I say unto you, and it hath gone forth in a firm decree, by the will of the Father, that mine apostles, the Twelve which were with me in my ministry at Jerusalem, shall stand at my right hand at the day of my coming in a pillar of fire, being clothed with robes of righteousness, with crowns upon their heads, in glory even as I am, to judge the whole house of Israel, even as many as have loved me and kept my commandments, and none else."  (Doctrine and Covenants 29:12)

Certain priesthood leaders have always been given the keys to judge members of the Church.  Bruce R. McConkie taught - 

“Be it remembered that the Twelve Apostles of the Lamb, who were with the Lord in his ministry in Jerusalem, shall judge the whole house of Israel, meaning that portion of Israel who have kept the commandments, ‘and none else.’ (D&C 29:12.) There will be a great hierarchy of judges in that great day, of whom Adam, under Christ, will be the chief of all. Those judges will judge the righteous ones under their jurisdiction, but Christ himself, he alone, will judge the wicked. (Bruce R. McConkie, The Millennial Messiah: The Second Coming of the Son of Man [Salt Lake City: Deseret Book Co., 1982], 584.)

Second - 

"For a trump shall sound both long and loud, even as upon Mount Sinai, and all the earth shall quake, and they shall come forth—yea, even the dead which died in me, to receive a crown of righteousness, and to be clothed upon, even as I am, to be with me, that we may be one."  (Doctrine and Covenants 29:13)

Which suggests to me that the righteous that have died since the resurrectteion of Jesus Christ, will be resurrected at that time.
