Revelation 18:1-3

Then I saw another angel descending from heaven, possessing great authority, and the earth was illuminated with his radiance and splendor.

• Notice all of the great messages that are coming from Heaven during the end times. John just keeps seeing them over and over. Remember that our Father showed Joel that there would be a great anointing during the end times, Acts 2:17-18. 
• Who does our Father use to deliver His messages? He uses His chosen ones. If we are not here, who will be giving these messages that illuminate the world?
• The messages of the end times are mighty for the whole earth, Revelation 5:9, Revelation 7:9

² And he shouted with a mighty voice, She is fallen! Mighty Babylon is fallen! She has become a resort and dwelling place for demons, a dungeon haunted by every loathsome spirit, an abode for every filthy and detestable bird.

• Babylon, the whore, the world’s economy will fall. Notice that beings are still involved in it though. It hasn’t been abandoned, it will just be defiled.
• Governments are corrupt, banks and wall street are corrupt. Preachers, politicians, and churches are corrupt, it seems that everyone only wants money and many are willing to do all kinds of evil to get it. The worlds economy is largely corrupt.
• Look at so many preachers today and see how their messages all evolve around money, buying a teaching series or giving a gift. 
• This is all evil. Our Lord told us to freely receive and freely give.
• Cure the sick, raise the dead, cleanse the lepers, drive out demons. Freely (without pay) you have received, freely (without charge) give. Matthew 10:8
• And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not. 2 Peter 2:3.

³ For all nations have drunk the wine of her passionate unchastity, and the rulers and leaders of the earth have joined with her in committing fornication (idolatry), and the businessmen of the earth have become rich with the wealth of her excessive luxury and wantonness.

• The anti-christ will require people to have a mark to buy or sell, so buying and selling will be going on during the end times. This means that most of what we are told in Revelation has to be spiritual. The flesh will be glorying as it never has before, 2 Timothy 3:2, but peoples spirits will be corrupted as they never have been before.
