Some horrible scenes in heaven!

I really cannot believe what I have read in Revelation. It is offensive.
Now, an angel whose splendour brightens up the earth came down from heaven. He announced the fall of Babylon. Of course, Babylon means Rome. The author predicted the fall of the Roman Empire (Revelation 18:1-2).
Then the author heard another voice coming from heaven to urge God' people to leave Babylon lest they would perish with her (Revelation 18:4-5). Rome would be burned.
The kings who used to committing fornication with the Roman Empire, stood far off and wept for the fate of Rome (Revelation 18:9).
they will stand far off, in fear of her torment, and say, "Alas! alas! thou great city, thou mighty city, Babylon!
In one hour has thy judgment come." (Revelation 18:10)
If one day is equivalent to 1000 years, one hour would be 41 years and 8 months.
The merchants who had grown rich from Rome also cried for her from afar, saying
In one hour all this wealth has been laid waste (Revelation 18:17).
The shipmasters, seafarers and sailors also stood far off and mourned.
And they threw dust on their heads, as they wept and mourned, crying out, "Alas, alas, for the great city
where all who had ships at sea grew rich by her wealth! In one hour she has been laid waste." (Revelation 18:19)
At last, a mighty angel took a millstone and threw it into the sea and cursed Rome, saying:
"So shall Babylon the great city be thrown down with violence, and shall be found no more;
and the sound of harpers and minstrels, of flute players and trumpeters, shall be heard in thee no more;
and a craftsman of any craft shall be found in thee no more;
and the sound of the millstone shall be heard in thee no more;
and the light of a lamp shall shine in thee no more;
and the voice of bridegroom and bride shall be heard in thee no more;
for thy merchants were the great men of the earth, and all nations were deceived by thy sorcery.
And in her was found the blood of prophets and of saints, and of all who have been slain on earth." (Revelation 18:21-24)
The voice of a great multitude from heaven sings Hallelujah to God.
The 24 elders and 4 living creatures fell down to worship God, saying "Amen, Hallelujah"
Then I heard what seemed to be the voice of a great multitude, like the sound of many waters and like the sound of mighty thunderpeals, crying, "Hallelujah! For the Lord our God the Almighty reigns.
Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready;
it was granted her to be clothed with fine linen, bright and pure" -- for the fine linen is the righteous deeds of the saints (Revelation 19:6-8).
Then heaven opens. A white horse appears. On this white horse, seats Faithful and True, and in righteousness he judges and makes war" (Revelation 29:11).  Who is this rider of the white horse? The author gave the answer:
He is clad in a robe dipped in blood, and the name by which he is called is The Word of God (Revelation 19:13).
Then I saw an angel standing in the sun, and with a loud voice he called to all the birds that fly in midheaven, "Come, gather for the great supper of God,
to eat the flesh of kings, the flesh of captains, the flesh of mighty men, the flesh of horses and their riders, and the flesh of all men, both free and slave, both small and great." (Revelation 19:17-18)
Then a battle was fought. On one side, there were the beast and the kings on earth. On the other side was the Word of God. The Word of God defeated them. The birds would feed on these corpses.

Dear Lord, teach us to be focussed, not to be greedy. May we put down our fragile argument and humbly invite You into our hearts, Amen.
