The Mark, the Name, the Number of the beast and the Tower of Babel = Ecumenism explains the context in full that surrounds the issuing of the Mark of the Beast.
The Final Mark of the Beast.
The final mark of the Antichrist (the Beast) will be willful knowingly on purpose representation of the damned individual’s name by gematria/isopsephia spelling of his name to equal 666. He will seek to impress this knowingly on all men. All who knowingly take it will be irrevocably damned.
The ancient types of this are the teserea: the mark on the right wrist (in the New Testament Greek wrist is included in reference to hand) or forehead, and the libellus: the certificate of apostasy the Roman pagan authorities granted to those who denied Christ.
The idea that computerized means to generate the final version of the libellus in this time and in connection a modern version of the teserea is most probable.
But is the spiritual mark that PRECEDES that which is the one by which men are damned. That is done knowingly when someone crosses over the line into willful subjection to the powers of darkness in complete understanding of what they are doing and complete will on their part to do it. These will be in complete docile subjection to the Antichrist to then take the physical mark.
That will be the final sign of the ones who DON’T take the mark to single them out for persecution unto death by the forces of the Antichrist.
9 And the third angel followed them, saying with a loud voice: If any man shall adore the beast and his image and receive his character in his forehead or in his hand,
10 He also shall drink of the wine of the wrath of God, which is mingled with pure wine in the cup of his wrath: and shall be tormented with fire and brimstone in the sight of the holy angels and in the sight of the Lamb.
11 And the smoke of their torments, shall ascend up for ever and ever: neither have they rest day nor night, who have adored the beast and his image and whoever receiveth the character of his name.
12 Here is the patience of the saints, who keep the commandments of God and the faith of Jesus.
13 ¶ And I heard a voice from heaven, saying to me: Write: Blessed are the dead who die in the Lord. From henceforth now, saith the Spirit, that they may rest from their labours. For their works follow them.(DRV)
