"And he (the beast from the land, the false prophet) 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 no one may buy or sell except one who has the mark, or the name of the beast, or the number of his name (666).” (vv.16-17)
Here in chapter 13 John describes two Beasts, one from “the sea” (vv.1-10) and one from “the land" (vv.11-18). Most Bible scholars believe the beast from the sea to be the “anti-christ,” and the beast from the land to be the "false prophet.”
The beast from the sea (the anti-christ) will more than likely come out from one of the European nations. John describes this beast as having, "seven heads, ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy" (v. 1). We are told in the book of Revelation that the seven heads are the seven mountains upon which the beast sits (rules), and that the ten horns are ten kings (also reinforced by the 10 crowns). He shall speak blasphemous things against God and "the world will marvel and follow the beast (anti-christ)” (v.3).
Now the beast from the land (the false prophet) will testify of the anti-christ causing many upon the earth to worship the first beast (v.12). He (the 2nd beast) will, "perform great signs, call fire down from heaven, deceive all those who dwell on the earth, and cause them to make an image of the first beast, and to worship the image or be killed” (vv.13-15). Finally we read in our text that, “he (the 2nd beast) 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 no one may buy or sell except one who has the mark, or the name of the beast, or the number of his name (666).”
Amazingly enough, there will be those during this tribulation period who will receive Jesus Christ as Lord: through the witness of the 144,000 who were sealed and sent out, and the two witnesses from chapter 7 who prophesied in Jerusalem for 1,260 days. These will refuse to worship the beast or take the mark of his name and become martyrs for Christ, but will enjoy everlasting life. Conversely, those who deny Christ and take the mark of the beast we are told in Revelation 14, "will drink of the wine of God's fury, which has been poured full strength into the cup of his wrath. He will be tormented with burning sulfur in the presence of the holy angels and of the Lamb” (vv.9-10).
As believers, we are sealed (marked) by the Holy Spirit, marking us as people belonging to Him, and preserving us for His kingdom. The mark of the beast similarly identifies men as his servants, and this mark will bring God’s full fury upon them. So, one who walks the earth during the tribulation period can either: 1) take the mark of Christ, probably die a martyr but rule and region with Him forever, or 2) take the mark of the beast, live for 1,260 days, but suffer for eternity. Everyone will be marked, the question is, which one will mark you?
The Truth: “A third angel followed them and said in a loud voice: "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. He will be tormented with burning sulfur in the presence of the holy angels and of the Lamb.” (Revelation 14:9-10)
