BarnumandBentley from Youtube gives us the following video.

Think it can’t happen? Don’t kid yourself.

He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads,  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. Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666. — Revelation 13:16-18 – 

But we are not to be afraid. We are to trust in God. He is our Strength, our Shield, our Provider and Healer.
