Revelation tells us what will happen to those who take the mark.
Revelation 14:10–11, describing the fate of someone who takes the mark of the beast, declares, “He also will drink the wine of God’s wrath, poured full strength into the cup of his anger, and he will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshipers of the beast and its image, and whoever receives the mark of its name.”
