“If anyone worships the beast and his image and receives his mark on the forehead or on the hand, he, too, will drink of the wine of God's fury, which has been poured full strength into the cup of his wrath.” Revelation 14:9,10
If you get the mark of the beast God’s complete wrath will be poured out on you.
Mark is required
“He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name.” Revelation 13:16-17
When the political-military leader known as the Beast rises to power, the world will ultimately be divided into two groups: those who obey the Beast and those who refuse. Remember, the mark will be tied to obedience.
The decision to accept or reject the mark will present a great world test. All people will face it. Those who take it will incur God’s wrath; those who refuse it will have God’s favor.
Soon everyone will be confronted with a choice of whom to obey—either God or the Beast.
