Revelation 15:2, 4

Then I saw something like a sea or large expanse of glass mixed with fire, and those who were victorious over the beast and over his image and over the number corresponding to his name were standing on the sea or large expanse of glass, holding harps of God [worshiping Him]. [Rev 4:6; 7:9-17]

“Who will not fear [reverently] and glorify Your name, O Lord [giving You honor and praise in worship]? For You alone are holy; For ALL THE NATIONS SHALL COME AND WORSHIP BEFORE YOU, FOR YOUR RIGHTEOUS ACTS [Your just decrees and judgments] HAVE BEEN REVEALED and DISPLAYED.” [Ps 86:9; Jer 10:7; Phil 2:9-11]
