The beast was given a mouth to utter proud words and blasphemies and to exercise its authority for forty-two months. 6 It opened its mouth to blaspheme God, and to slander his name and his dwelling place and those who live in heaven. 7 It was given power to wage war against God’s holy people and to conquer them. And it was given authority over every tribe, people, language and nation. (Revelation 12:5-7 NIV).
When the antiChrist comes he will blaspheme God and will have the power to defeat God’s saints in battle for three and a half years (see Daniel 7:25). What this probably means is that the Antichrist will conquer all the powerful countries in the world and force them to surrender believers in Jesus Christ up for Martyrdom. Notice that this time of conquest and complete power only lasts for three and a half years, not for seven. To me, this means that he will not have complete political control until the second half of Daniel’s “70th week” (Daniel 9:27 NIV). He will be admired and known all over the world during the first half of the seven years, but not until the halfway point will he overpower his enemies and take complete control.
