Thematic Bible: The angel having the everlasting gospel

And I saw an angel fly in the midst of heaven having an everlasting gospel, to preach unto them that sit and dwell on the earth, and to all nations, kindreds, and tongues, and people, saying with a loud voice, "Fear God and give honour to him, for the hour of his judgment is come: and worship him, that made heaven and earth, and the sea, and fountains of water."
