Revelation 14:6-8

Then I saw another angel flying in midheaven, with an eternal gospel to preach to the inhabitants of the earth, to every nation and tribe and language and people; [Rom 1:1-4; 1 Cor 15:3-5; Gal 1:6, 7] and he said with a loud voice, “Fear God [with awe and reverence], and give Him glory [and honor and praise in worship], because the hour of His judgment has come; [with all your heart] worship Him who created the heaven and the earth, the sea and the springs of water.” Then another angel, a second one, followed, saying, “Fallen, fallen is Babylon the great, she who has made all nations drink the wine of the passion of her immorality [corrupting them with idolatry].” [Is 21:9; Dan 4:30, 31; Rev 17:2]
