Some say it’s the most evil number in history. Others say it will be the primary way to identify history’s most evil man in the future.
But wherever one stands on Bible prophecy, there is no doubt about the intrigue surrounding the number 666 and its role in the book of Revelation.
The following pages highlight six things you should know about this number.
Got Questions states: At the close of Revelation 13, which discusses the beast (the Antichrist) and his false prophet, we read, “This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666” (Revelation 13:18). Somehow, the number 666 is a clue to the identity of the beast. Revelation 13 also mentions the “mark of the beast” (verses 16–17), and popular thought often links 666 with the mark; however, the mark of the beast and 666 appear to be two different things. The mark of the beast is something people must receive in order to buy and sell. The number 666 is somehow associated with the beast/Antichrist as “his” number. More Here
