As world governments become more interconnected with the use of advanced technology, it will become easier for them to monitor their citizens. The Bible says the antichrist will have more than just political control of the world. It says he will have the power to control all financial transactions through the use of a special mark.
“And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name” (Rev 13:16-17).
