Mark of the Beast
"And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, the same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: and the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name. Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus." ~ Revelation 14:9-12
In the issue of the great contest, two distinct, opposite classes are developed. One class " worship the beast and his image, and receive his mark," and thus bring upon themselves the awful judgments threatened by the third angel. The other class, in marked contrast to the world, "keep the commandments of God and the faith of Jesus." Though the powers of earth summon their forces to compel "all, both small and great , rich and poor, free and bond," to receive the mark of the beast, yet the people of God do not receive it. The prophet of Patmos beholds " them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God," and singing the song of Moses and the Lamb.
