The great event is thus described by John the Revelator:
"And I saw another angel fly in the midst of heaven, having the
everlasting gospel to preach unto them that dwell on the earth, and
to every nation, and kindred, and tongue, and people, saying with
a loud voice, Fear God, and give glory to him: for the hour of his
judgment is come" (Rev. xiv, 6, 7).
