Then a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both the number of their fellow servants and their brethren, who would be killed as they were, was completed. Revelation 6:11
One way to get back at someone who killed you would be to come back as a ghost to haunt them. Perhaps asking "why?" endless times, making suggestions regarding their personal hygiene, hiding their car keys, or just showing up bloodied with wide staring eyes while pointing spectrally at them during their finer moments. That is how the story or joke usually goes anyway. Whether that can happen or not, I do not know.
As I look into the issue in the Revelation, one place to look is the tribulation saints whose souls are under the altar when the fifth seal is broken by the Lamb. They do not get to go back and haunt their killers but are told to rest for a little while longer. Another group would be those who have gone to sleep in Christ before the great tribulation, but it seems that they too, raised up in the Rapture, only follow Christ the Lord on white horses as He returns to deal with those armies arrayed against His city.
Therefore, one might conclude that once our Lord Jesus has us in Heaven with Him, that He will never give up His own. No ghostly missions to dispense a little justice to the killers? Nope, only a good Shepherd who will never give up His sheep. Amen! Once we are with the Lord Jesus, I don't think we will want to go anywhere else.In Christ, Bucky
