The Bible says that the Antichrist will cause everyone to take a mark on their right hand or forehead. Without this mark no one will be able to buy or sell. The Bible does not say much about this mark but it does say that all those who take the mark of the beast will be eternally damned. And those who refuse to take the mark will be put to death for their rebellion against the Antichrist and his new world order. Taking the mark of the beast shows alligence to both the Antichrist and the devil and is unforgivable in God's eyes. Many Christians will die for their faith during the great Tribulation which is the final three and a half years before Jesus returns. Christians realize that there is no hope for those who take the mark of the beast but sadly there will be some Christians that will take the mark. This will be truly tragic for they will not be able to enter Heaven. The great Tribulation will be a very terrible time for all of mankind. In 2021, I dreamt that the COVID vaccine was the mark of the beast even though I don't believe that it is I know that the vaccine is the precursor to the mark of the Beast!
