“He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name. This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is man’s number. His number is 666” (Rev. 13:16-18).
The mark of the beast, which will be universally issued around the entire world, MUST NOT be received under any circumstances, even by Christians! Scripture goes on to say that all who take the mark will be tormented with burning sulfur (Rev. 14:9-12).
