This may be a “hard saying” for some but if we love God then we Love All of His attributes and the Whole Bible. This is the very reason why Churches and most Christians Avoid Bible Prophecy altogether.
The view in Re. 17-18 is what happens on the path to Armageddon. This is Gods Righteous Wrath being poured out upon the Wicked for Corrupting the World which He Created and for Persecuting His Children. And most of all for Hating Him and His son Jesus and His Word. The cup is full and the time has come.
His Endless Love and Mercy has been shown and now the world will see some of Gods other Attributes such as Righteous Judgment,Justice,Holiness and Divine Wrath.Note the Holiness of God and how all those in heaven Rejoice.
Revelation 16:17-21 (NKJV) 17 Then the seventh angel poured out his bowl into the air, and a loud voice came out of the temple of heaven, from the throne, saying, “It is done!” 18 And there were noises and thunderings and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth.
19 Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath. 20 Then every island fled away, and the mountains were not found. 21 And great hail from heaven fell upon men, each hailstone about the weight of a talent. Men blasphemed God because of the plague of the hail, since that plague was exceedingly great.
Revelation 19:1-21 (NKJV) 1 After these things I heard a loud voice of a great multitude in heaven, saying, “Alleluia! Salvation and glory and honor and power belong to the Lord our God! (Angels Rejoicing.)
2 For true and righteous are His judgments, because He has judged the great harlot who corrupted the earth with her fornication; and He has avenged on her the blood of His servants shed by her.”
3 Again they said, “Alleluia! Her smoke rises up forever and ever!”
4 And the twenty-four elders and the four living creatures fell down and worshiped God who sat on the throne, saying, “Amen! Alleluia!”
5 Then a voice came from the throne, saying, “Praise our God, all you His servants and those who fear Him, both small and great!”
6 And I heard, as it were, the voice of a great multitude, as the sound of many waters and as the sound of mighty thunderings, saying, “Alleluia! For the Lord God Omnipotent reigns!
10 And I fell at his feet to worship him. But he said to me, “See that you do not do that! I am your fellow servant, and of your brethren who have the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy.”
11 Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war.
12 His eyes were like a flame of fire, and on His head were many crowns. He had a name written that no one knew except Himself. 13 He was clothed with a robe dipped in blood, and His name is called The Word of God.
14 And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses. 15 Now out of His mouth goes a sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God.
16 And He has on His robe and on His thigh a name written: KING OF KINGS AND LORD OF LORDS.
17 Then I saw an angel standing in the sun; and he cried with a loud voice, saying to all the birds that fly in the midst of heaven, “Come and gather together for the supper of the great God, 18 that you may eat the flesh of kings, the flesh of captains, the flesh of mighty men, the flesh of horses and of those who sit on them, and the flesh of all people, free and slave, both small and great.”
19 And I saw the beast, the kings of the earth, and their armies, gathered together to make war against Him who sat on the horse and against His army.
20 Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshiped his image. These two were cast alive into the lake of fire burning with brimstone.
21 And the rest were killed with the sword which proceeded from the mouth of Him who sat on the horse. And all the birds were filled with their flesh.
