Rev. 13:7 – And he was permitted to wage war against the saints and to conquer them. He was also given authority over every tribe, people, language, and nation.
Take note of the sinister will of Satan and the permissive will of God. The dragon gives the beast his power, authority and throne (v. 2). The beast’s fatal would is healed (v. 3a.). The whole earth is amazed and follows the beast (v. 3b). They worship the dragon … and worship the beast (v. 4). A mouth is given to the beast to speak boasts and blasphemies, and he is given authority to act for 42 months (v. 5).
So far, the emphasis is on the work of Satan, manipulating the beast. But things begin to turn in verse 7, where it becomes clear that God permits the evil to take place. The beast is permitted to wage war against the saints and to conquer them. He is given authority over every tribe, people, language and nation (v. 7). All those who live on the earth will worship him, everyone whose name is not written from the foundation of the world in the book of life of the Lamb who is slaughtered (v. 8).
