Mark of confusion
Note CV short = coronavirus shot= COVID-19 vaccine.
The theCOVID-19 vaccine has set new rounds of speculation over the mark of the beast. I don't believe it is the beast's mark because of the timing mostly and the refutations given in this video. Pauls states in 2 Thessalonians 1:1-7 The antichrist must come; his deception must spread after God lifts the restraint off the earth. However, if mark-like restrictions are put in place, such as the vaccine passport, it will condition people to accept the mark in the future.
This video mentions other speculations and refutes them with scripture and the meaning of keywords in the original Greek. He argues it would not be implantable because of the definition of epi, the Greek word best translated as on. It is a literal mark because the Greek word translated as such is a physical identifying mark. In light of this, I think it will be Satan's counterfeit of the Seal of the Spirit that Paul mentions in Ephesians 1:13-14. It will identify those who have sided with the beast just as the Spirit identifies those belonging to God.
In contrast to those sealed with the Spirit (Ephesians 4:30), God will send those people with the mark to the lake of fire (Revelations 14:9-11). Being sneaky as he is, the beast sets a commerce restriction to entice more people to survive. (Revelation 13:16-17)
In light of the meaning of this mark's original words and description in Revelation 13, a barcode-like mark would be most likely. However, as the video states, the barcode's invention did not signal the mark's arrival. This is the problem with speculation gone wild that is promoted as fact, especially of things not explicitly mentioned in scripture. People would do well to qualify their statements, so it obvious that is just speculation. Truthfully, we don't know what the mark will look like. So, just as Revelation 13:18 says with the beast's number 666, it calls for wisdom.
So rest assured if you take the vaccine, you are not damning yourself to eternal death. But if you don't take the vaccine and go along with the potential restrictions, be mindful of what you are getting yourself into.
