Timothy LaHaye, who has done dozens of books on the book of Revelation, is convinced that the “Mark of the beast” described by John in the book is going to be a barcode. Look around your house, in your wallet, in your dresser drawer, on your keychain. Every card, every grocery store savings card, every bank account, everything and anything which contains information has an alphanumeric code attached. LaHaye believes that when John’s foretold Revelation does come to pass, the mark of the beast will be a bar code which contains information from every facet of your life. The mark of the beast will be the key to every earthly thing you desire, enjoy or possess.

I only put this in here because it sprang into the forefront of my brain. As John and the Bible tell us, We shouldn’t watch for signs, as only God knows when the time will come. Still, we as Christians must always be wary of that which tethers us to the world.
