Blacksword:
You asked: “Doesn't 666 equate to WWW in Hebrew?”
The answer is…sort of. That is, it may be that “w” is the letter equivalent of the number 6. But that is not how the “number of a man” is determined. it is the adding up of the numbers represented by all the letters in the full name that must add to 666. This means taking someone’s full name at birth, translating it into Hebrew, converting the Hebrew letters into their number equivalents, and adding up all of those numbers.
You then comment: “We shall not be able to buy or sell without the mark, right? Does that mean the Internet is the Antichrist and unless we are all on line we'll not be able to trade in the Antichrists kingdom on Earth?...It is said that all UPC barcodes contain the number 666. Is the barcode the mark of the Antichrist?”
The Scripture is clear concerning the “mark”:
“He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their forehead. 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.” (Rev. 13:16-17)
Thus, neither the Internet nor the UPC bar code can be the “mark,” since it is not “on their right hand or on their forehead. The mark is clearly a “branding” of some sort (or perhaps the scar left by the insertion of a microchip?...) And it is something that the Antichrist will require everyone (no matter how wealthy or poor) to have if they want to transact business of any type – from buying a container of milk to trading stocks. [N.B. The UPC barcode does have a “version” of “666”: the first, middle and last “numbers” represented in the barcode are all “6.”)
This is why refusing the “mark of the beast” is one’s last opportunity to choose which “side” their on: Jesus’ or Satan’s. Once a person accepts the “mark,” there is no turning back; there is no further opportunity to accept Christ. It is the final choice to accept Christ and live “off the grid” - trusting in His promises to provide for your needs - or rejecting Christ completely, and accepting life under Satan’s terms.
Note that I am not making a moral judgment here. I am simply explaining this issue from the Christian point of view. As always, you are free to accept or reject it, and I love you no less.
Peace.
