Verse 2: "And I saw what appeared to be a sea of glass mingled with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands."

"sea of glass" symbolizes the Revelation of Baha'u'llah which is clear, like "glass," with the explanations and commentaries of the Lamb—how easy this Revelation is to understand. The other revelations of previous Manifestations are like rivers that lead to the sea.

It is "mingled with fire" showing that the nuclear holocaust must take place in order for God's Revelation to be established.

Those who are "standing beside the sea of glass" are the people who become believers in Baha'u'llah or come out of the great violation of the Covenant-breakers, through the Lamb's explanations and commentaries; and of course of the other revelations, like Christians, that are now coming into the Revelation of Baha'u'llah by the Lamb's explanations.
