“And I saw what seemed to be a glassy sea mingled with fire, and those who come off victorious from the wild beast and from its image and from the number of its name standing by the glassy sea, having harps of God.”​—Revelation 15:2.

The singers that John sees “come off victorious from the wild beast and from its image and from the number of its name.” So they must be those from among the 144,000 who live on earth during the last days. As a group, they do indeed come off victorious. For almost 90 years since 1919, they have refused to accept the mark of the wild beast or look to its image as man’s only hope for peace. Many of them have already endured faithful to the death, and these, now in heaven, doubtless follow with special delight the singing of their brothers who are still on earth.​—Revelation 14:11-13.
