The Mark of the Beast (666)
What does the bible say about the Mark of the Beast?

Revelations 13:  15-18	Revelations 14: 9-11
He was given power to give breath to the image of the first beast, so that it could speak and cause all who refused to worship the image to be killed. He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name.  This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is man's number. His number is 666.	A third angel followed them and said in a loud voice: "If anyone worships the beast and his image and receives his mark on the forehead or on the hand, he, too, will drink of the wine of God's fury, which has been poured full strength into the cup of his wrath. He will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. And the smoke of their torment rises for ever and ever. There is no rest day or night for those who worship the beast and his image, or for anyone who receives the mark of his name. (which was 666)"
There is a lot of speculation on how this will all turn out, but you can be sure of this... ANYONE who gets the mark of the beast 666 is DOOMED!  There is NO turning back, NO forgiveness, NO 2nd chances, NO redemption, No salvation! There is no hoping that, "God will understand, He'll forgive me for taking the mark, He's merciful and He doesn't want me to lose my life. I don't have to worry, I can still be saved, right?"  WRONG!!!! If you get this mark of the beast 666 on your forehead or your hand, you're finished!  You will NOT be saved!  You have claimed loyalty to the beast.  There will be great stress and tribulation at the time the mark is given out. It will probably seem like the best thing to do to survive, solving many problems. Great pressure will be upon you to get it, like torture, lose of life, lose of job, lose of children, lose of possessions, reputation, house, freedoms, limbs, etc.  Prophets have been warned that the devil will not want to let those who refuse off with a simple beheading, but he will have them gruesomely tortured to get them to take his mark. You won't be able to buy or sell anything without the mark.  At that point in time, you MUST be ready to die rather than get the mark.  You must be ready to face execution rather than take the mark of the beast, no matter what the punishment.  Don't compromise, and make no mistake about it, those who get the mark, even believers, will be CONDEMNED to God's full wrath forever!

But there is hope for those who refuse to take the Mark of the Beast and are killed for their faith.

Revelations 20:4

I saw thrones on which were seated those who had been given authority to judge. And I saw the souls of those who had been beheaded because of their testimony for Jesus and because of the word of God. They had not worshiped the beast or his image and had not received his mark on their foreheads or their hands. They came to life and reigned with Christ a thousand years.
