The Urantia Book, Paper 47 – The Seven Mansion Worlds
47:10:2 (539.4) He recorded: “And I saw as it were a sea of glass mingled with fire; and those who had gained the victory over the beast that was originally in them and over the image that persisted through the mansion worlds and finally over the last mark and trace, standing on the sea of glass, having the harps of God, and singing the song of deliverance from mortal fear and death.” (Perfected space communication is to be had on all these worlds; and your anywhere reception of such communications is made possible by carrying the “harp of God,” a morontia contrivance compensating for the inability to directly adjust the immature morontia sensory mechanism to the reception of space communications.)
