Finkenstein, Revelation 13 tells what will follow. First of all, people in general will feel good about the new global authority. The Bible says:
3...and all the earth followed the wild beast with admiration. 4 And
they worshipped the dragon because it gave the authority to the wild
beast, and they worshipped the wild beast with the words: “Who is like
the wild beast, and who can do battle with it?”
And after that Revelation 13:6,7 predicts that this global authority will start a war against the holy ones. That means trouble for believers in the true God.
6 And it opened its mouth in blasphemies against God to blaspheme his name and his dwelling place, even those residing in heaven. 7 It was permitted to wage war with the holy ones and conquer them, and it was given authority over every tribe and people and tongue and nation.
But there is hope for those who manage to flee to a safe place before it is too late, like the christians that fled Jerusalem in year 66 CE right after the Roman armies retreated.
