A cashless economy will be another big step. Now we have debit cards but they're moving all the time toward a physical mark/tattoo/implant of some kind in place of the cards. Before the mark is forced on the world, though, a lot will happen. The economy will collapse and a 'savior' will appear with a solution. He will be the embodiment of Satan himself. He will be in charge when the mark is dictated and you will have to deny Christ to get it.

“In a time of deceit telling the truth is a revolutionary act.”
― George Orwell

It's not over when you lose. It's over when you quit.
