"Then one of the seven angels who had the seven bowls came and said to me, “Come, I will show you the judgement of the great prostitute who is seated on many waters, 2 with whom the kings of the earth have committed sexual immorality, and with the wine of whose sexual immorality the dwellers on earth have become drunk.” 3 And he carried me away in the Spirit into a wilderness, and I saw a woman sitting on a scarlet beast that was full of blasphemous names, and it had seven heads and ten horns. 4 The woman was arrayed in purple and scarlet, and adorned with gold and jewels and pearls, holding in her hand a golden cup full of abominations and the impurities of her sexual immorality. 5 And on her forehead was written a name of mystery: “Babylon the great, mother of prostitutes and of earth's abominations.” 6 And I saw the woman, drunk with the blood of the saints, the blood of the martyrs of Jesus. When I saw her, I marvelled greatly."
Revelation 17:1-6
Another new section now begins, embracing this and the next two chapters, and again the theme corresponds to that of previous sections. In the second half of the book, from chapter 12 onwards we have been introduced to the enemies of Christ, the dragon, the beast, the false prophet, Babylon and the men with the mark of the beast. John deals with the overthrow of these enemies one by one, but in reverse order.' Thus, in chapters 15/16, the judgment of impenitent men is before us, and now in chapter 17, the fall of Babylon is dealt with. (The destruction of the beast and the false prophet comes in chapter 19 and the final overthrow of the dragon in chapter 20). These judgments are not to be thought of as consecutive so much as more or less simultaneous, although obviously they must be described one after the other, and this is borne out by the fact that both in these later chapters and earlier in the book we have had descriptions of the judgment day (cf 6:12; 11:19; 14:19; 16:21). Now John has already mentioned Babylon on two occasions, in chapter 14:8 and in 16:19, and obviously he must sooner or later deal with the subject more fully, and elaborate it for us. This he now proceeds to do, at length. Before we turn to this, however, we must note something that is becoming increasingly clear and significant. The tone of these later chapters is changing. We have read through and studied some very grim and frightening passages that have made our hearts almost fail within us for fear, at the thought of what will yet come upon the earth in the last days. But now we have the steady emphasis upon the victory of Christ over the powers of darkness and the rejoicing of the saints of God in that victory. It is as if we were beginning to emerge from the dark and terrifying crisis of history - into the glow and assurance of the triumph of God. John has not hidden from us the very worst that Satan can do to the Church; but having said this he can still say something deeper and more wonderful, that the victory lies with Christ. And as we read on, this emphasis becomes more and more pronounced until in the end we are caught up in the vision of the new heaven and the new earth and the eternal reign of God and of His Christ.
