Q. Do you think taking the mark of the beast involves something far more sinister than just a means of controlling buying and selling, perhaps the changing of your DNA and your very soul belonging to Satan?
A. Lately there are several theories on what the mark really is and how it will affect the people who take it. None of these theories are mentioned in the Bible and are merely human speculation. The clear Biblical facts are that people who take the mark will have been warned in advance that doing so will place them forever outside of God’s saving grace and will choose to do so in spite of this. Rev. 14:9-11 spells it out.
A third angel followed them and said in a loud voice: “If anyone worships the beast and his image and receives his mark on their forehead or on their hand, they, too, will drink the wine of God’s fury, which has been poured full strength into the cup of his wrath. They will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. And the smoke of their torment will rise for ever and ever. There will be no rest day or night for those who worship the beast and his image, or for anyone who receives the mark of his name.”
To me the technology involved or how it may change people is irrelevant. Whatever it turns out to be, people will know exactly what the mark is, what taking it means, and that God has warned them not to take it. No one can be tricked into taking it without their knowledge or against their will. Nor can they do so by accident. Otherwise God could not hold them accountable for taking it.
