One has stated to me: "Christ said he would Share His Throne with us as His Father has Shared His Throne with Christ His Only Chosen Son."
My reply:
"He who has an ear, let him hear what the Spirit says to the churches. He who overcomes shall not be hurt by the second death."' - (Revelation 2:11, New King James)
He who overcomes, I will give to him to sit down with me on my throne, as I also overcame, and sat down with my Father on his throne. - (Revelation 3:21, World English)
I can say that Jesus said he would share his throne with those who overcome as he did, to the extent that they could no longer be harmed by the second death. Paul, in Philippians 3:12-14 declares that he, at least at the time he wrote that letter, did not believe that he had not yet attained that perfection, a perfection of faith that is so firm that it is impossible for it to be shaken, and thus be hurt by the condemnation beyond that which is in Adam.
