For verily I say unto you, That he [Christ] shall come; and he that layeth down his life for my sake and the gospel’s, shall come with him, and shall be clothed with his glory in the cloud, on the right hand of the Son of Man. (JST Mark 8:43)
It seems that all the martyrs will participate in the second coming of Christ! I suppose we will see Joseph Smith, Hyrum Smith, all the missionaries who were killed, all the former-day saints who were martyred, all the prophets who were killed for their messages, and any of us who give our lives for the truth. These saints are privileged to come specifically because they suffered death rather than deny the faith. In a sense, they overcame death.
Jude wrote about this in his general epistle in the Bible, but not with so much information about who but with more information about what they would do:
14 And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
15 To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him. (Jude 1:14-15)
It seems those who have overcome in this way we be given the privilege of cleaning up the evil in the world because they would not submit to it during mortality regardless of the consequences. This will be the day of their complete triumph because they will finally get their way, and they can’t be gotten rid of like they were before because they will be resurrected.
Ah, beautiful day…. (happy sigh of anticipation)
