Then I saw thrones, and those who sat on them were given the power to judge. I also saw the souls of those who had been executed because they had proclaimed the truth that Jesus revealed and the word of God. They had not worshiped the beast or its image, nor had they received the mark of the beast on their foreheads or their hands. They came to life and ruled as kings with Christ for a thousand years. 1
