The Bible does not use the phrase “one-world government” or “one-world currency” in referring to the end times. It does, however, provide ample evidence to enable us to draw the conclusion that both will exist under the rule of the Antichrist in the last days.
In his apocalyptic vision in the Book of Revelation, the Apostle John sees the “beast,” also called the Antichrist, rising out of the sea having seven heads and ten horns (Revelation 13:1). Combining this vision with Daniel’s similar one (Daniel 7:16-24), we can conclude that some sort of world system will be inaugurated by the beast, the most powerful “horn,” who will defeat the other nine and will begin to wage war against Christians. The ten-nation confederacy is also seen in Daniel’s image of the statue in Daniel 2:41-42, where he pictures the final world government consisting of ten entities represented by the ten toes of the statue. Whoever the ten are and however they come to power, Scripture is clear that the beast will either destroy them or reduce their power to nothing more than figureheads. In the end, they will do his bidding.
John goes on to describe the ruler of this vast empire as having power and great authority, given to him by Satan himself (Revelation 13:2), being followed by and receiving worship from “all the world” (13:3-4), and having authority over “every tribe, people, language and nation” (13:7). From this description, it is logical to assume that this person is the leader of a one-world government which is recognized as sovereign over all other governments. It’s hard to imagine how such diverse systems of government as are in power today would willingly subjugate themselves to a single ruler, and there are many theories on the subject. A logical conclusion is that the disasters and plagues described in Revelation as the seal and trumpet judgments (chapters 6-11) will be so devastating and create such a monumental global crisis that people will embrace anything and anyone who promises to give them relief.
Once entrenched in power, the beast (Antichrist) and the power behind him (Satan) will move to establish absolute control over all peoples of the earth to accomplish their true end, the worship Satan has been seeking ever since being thrown out of heaven (Isaiah 14:12-14). One way they will accomplish this is by controlling all commerce, and this is where the idea of a one-world currency comes in. Revelation 13:16-17 describes some sort of satanic mark which will be required in order to buy and sell. This means anyone who refuses the mark will be unable to buy food, clothing or other necessities of life. No doubt the vast majority of people in the world will succumb to the mark simply to survive. Again, verse 16 makes it clear that this will be a universal system of control where everyone, rich and poor, great and small, will bear the mark on their hand or forehead. There is a great deal of speculation as to how exactly this mark will be affixed, but the technologies that are available right now could accomplish it very easily.
Those who are left behind after the Rapture of the Church will be faced with an excruciating choice—accept the mark of the beast in order to survive or face starvation and horrific persecution by the Antichrist and his followers. But those who come to Christ during this time, those whose names are written in the Lamb’s book of life (Revelation 13:8), will choose to endure, even to martyrdom.
