The Mark of the Beast

The Mark of the Beast, or 666 is well known in popular culture, it is seen in books and movies and even music. If you go into any bookstore or Christian store you will find lots of books on the Mark of the Beast and what it means. I think the earliest movie that I remember seeing is the Omen though you can find lots of movies that deal with the subject in biblical prophecy, both documentaries and fictional. 
Many people treat the Mark of the Beast like it is a horror story, something they see in movies and read about in books, but ultimately not real. People think that no one can force them to get a mark on their hand or forehead, not in this free country. Well most people will not have to worry about getting this Mark. The Rapture will have occured first and the church will have been taken out of the world along with the Holy Spirit. The Antichrist will then rise up and take control of the world, the Bible does not specify how long it is between the time the Antichrist takes power and then signs a peace treaty with Israel, which included rebuilding the Temple. This treaty will be the beginning of the Tribulation period. 
²⁷ He will confirm a covenant with many for one ‘seven.’^[h] In the middle of the ‘seven’^[i] he will put an end to sacrifice and offering. And at the temple^[j] he will set up an abomination that causes desolation, until the end that is decreed is poured out on him. Daniel 9:27
In the middle of this peace treaty, the Antichrist will enter the Temple and declare himself God. 
³ Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness^[a] is revealed, the man doomed to destruction. ⁴ He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God. 2 Thessalonians 2:3-4
At some point, the Antichrist is killed with a wound to his head. In a poor imitation of Jesus rising from the grave, the Antichrist will rise from the dead and his deadly wound will be healed. 
³ One of the heads of the beast seemed to have had a fatal wound, but the fatal wound had been healed. The whole world was filled with wonder and followed the beast. Revelation 13:3
After the Antichrist rises from the dead, he is indwelt with Satan. The Antichrist is not God, he is actually dead, only through Satan indwelling him can he rise from the dead. 
The Antichrist has a helper, the False Prophet. When the Antichrist rises from the dead, the False Prophet erects a statue of the Beast and enforces a system where all people have to have a mark on their right hand or forehead. A system of worship in enforced where all people must bow down and worship this statue and all those that refuse to take the Mark will be killed. 

¹¹ Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon. ¹² It exercised all the authority of the first beast on its behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed. ¹³ And it performed great signs, even causing fire to come down from heaven to the earth in full view of the people. ¹⁴ Because of the signs it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth. It ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived. ¹⁵ The second beast was given power to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship the image to be killed. ¹⁶ It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads, ¹⁷ so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name.
¹⁸ This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man.^[e] That number is 666.         Revelation 13:11-18

Now you may be thinking, couldn't people fake the Mark? The answer is no, sure they could fake it from a distance, but the Mark will actually be a microchip inserted in their hand or forehead that will be scanned. This is scary, but scarier still is the fact that the technology exists today. Most pets are now "chipped" in case they get lost. The chip is an RFID microchip that is about the size of a grain of rice.

Are you thinking that no one is using the technology right now? There are certain private and government agencies that require their employees to be chipped as a method of entering the secure facility. Article
Many institutions are now starting to use RFID technology, for example prisons are starting to use RFID to track their inmates. They do not have to have a chip implanted, just an ankle bracelet at this time. Article
Schools are also starting to make their students wear a name badge with an RFID chip. Article
In the preliminary versions of the Obamacare healthcare bills there was a measure that would require all those on public healthcare to be required to have a chip implanted with their medical history. None of these versions made it to the final bill. Article


As you can see, the technology is very real. I would not worry about getting a chip or accidentally taking the Mark of the Beast. When this system is implemented there will be no doubt as to what you are doing. You would never be able to take the Mark accidentally.
