A third angel followed them and said in a loud voice: “If anyone worships the beast and its image and receives its mark on their forehead or on their hand, 10 they, too, will drink the wine of God’s fury,which has been poured full strength into the cup of his wrath. They will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. 11 And the smoke of their torment will rise for ever and ever. There will be no rest day or night for those who worship the beast and its image, or for anyone who receives the mark of its name.” 12 This calls for patient endurance on the part of the people of God who keep his commands and remain faithful to Jesus. (Revelation 14:9-12 NIV)
Not everyone who is alive during the tribulation period will suffer God’s wrath. Those who truly believe in Jesus Christ will not take the mark of the beast, and will eventually be rewarded.
However, it will take a lot of faith in order to follow God’s commands in that day. In this case God’s “commands” are that we do not take the mark of the beast. Those who truly believe will know that those who take the Mark will go to hell for eternity. Therefore, for those who are true believers the choice will be easy: Don’t take the mark!
Further reading about endurance:
“Then you will be handed over to be persecuted and put to death, and you will be hated by all nations because of me. 10 At that time many will turn away from the faith and will betray and hate each other, 11 and many false prophets will appear and deceive many people. 12 Because of the increase of wickedness, the love of most will grow cold, 13 but the one who stands firm to the end will be saved. 14 And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come. (Matthew 24:9-14 NIV)
