“In the issue of the contest all Christendom will be divided into two great classes—those who keep the commandments of God and the faith of Jesus, and those who worship the beast and his image and receive his mark. Although church and state will unite their power to compel “all, both small and great, rich and poor, free and slave” (Revelation 13:16), to receive “the mark of the beast,” yet the people of God will not receive it. The prophet of Patmos beholds “those who have the victory over the beast, over his image and over his mark and over the number of his name, standing on the sea of glass, having harps of God” and singing the song of Moses and the Lamb. Revelation 15:2, 3”
