The man of sin already came, it is the Roman popes, which is why the prostitute of Babylon is seated in the seven mountains of Rome, which is Vatican City, and she rules over all the kings of the earth through money, for all the central banks of the world issue her form of money to all the inhabitants of the world, which is paper money and fiat currency, and that is why when she is destroyed by the 10 nations that give their authority to the USE the entire financial system will collapse, for the "merchants of the earth will wail for her, for no one buys their merchandise anymore", because paper money and fiat currency will suddenly become worthless. This is the truth, and most people in the world already have the mark of the beast, through ignorance. It is money itself, and God has wisely chosen it to be this to condemn the world through money, and to test the inhabitants of the world to see who truly obeys the commands of God and leaves the financial system, hence "come out of her my people, so that you do not partake in her plagues".
