REVELATION 14.6 I saw an angel flying in mid heaven, having an eternal Good News to proclaim to those who dwell on the earth, and to every nation, tribe, language, and people. 14.7 He said with a loud voice, “Fear the Lord, and give him glory; for the hour of his judgment has come. Worship him who made the heaven, the earth, the sea, and the springs of waters!”
14.8 Another, a second angel, followed, saying,
“Babylon the great has fallen, which has made all the nations to drink of the
wine of the wrath of her sexual immorality.”
14.9 Another angel, a third, followed them, saying
with a great voice, “If anyone worships the beast and his image, and receives a
mark on his forehead, or on his hand, 14.10 he also will drink of the wine
of the wrath of God, which is prepared unmixed in the cup of his anger. He will
be tormented with fire and sulfur in the presence of the holy angels, and in
the presence of the Lamb. 14.11 The smoke of their torment goes up forever
and ever. They have no rest day and night, those who worship the beast and his
image, and whoever receives the mark of his name.
14.12 Here is the perseverance of the saints, those
who keep the commandments of God, and the faith of Jesus.” 14.13 I heard a
voice from heaven saying, “Write, ‘Blessed are the dead who die in the Lord
from now on.’” “Yes,” says the Spirit, “that they may rest from their labors;
for their works follow with them.” -WEB Bible.
Three angels have a message of Hope as well as messages of Warning. They are letting people know that there's still a slim opportunity remaining, but there's no time left for delay. Procrastination is the worst you can do: the time to repent before the Lord Jesus Christ is NOW.
Things are about to get so bad on planet earth that you're better off dead. In fact, you are BLESSED if you're dead and safely gathered with all the other believers in heaven: because you don't want to be on earth when God's angels pour out the full, potent, undiluted fury of God’s wrath.
