SEA OF GLASS . One of the features of the heavenly landscape described in Revelation 4:6; Revelation 15:2 . By its side stood those who had been victorious in the struggle with the beast, singing to the glory of God. Its location was apparently before the throne of God. Just what the symbolism here intended is, it is difficult to state. The probability is, however, that there is no distinct symbolism whatever, but that the reference is rather to the brilliancy of the waters as one element in the supremely beautiful land of heaven.
