Babylon has been the centre, under successive dynasties, of a world empire, including not only part of Asia, but reaching west to Europe and south to Africa. It sat practically in the connecting strip of Orient and Occident, ruling over both. In the dim dawn of history a God-ignoring, and so really a God-defying and man-exalting movement, centred in the city called Babel. And from that time on that city, and its successor Babylon, have seemed as though possessed with a spirit of antagonism to God and His people. It is as though it were the earthly headquarters of the blasphemous unseen evil forces. This is a simple bit of geography lesson in the Old Testament. This is the map that lies ever open in these older pages, with its two capital cities marked large. And this indicates the area of the storm, and the two central points where its outburst will centre. Studying the Weather Forecast. It is interesting to find a weather forecast of this storm. The old Hebrew prophets were close students of national and world-wide weather conditions, and much given to making forecasts of impending storms. Even in the New Testament there is this distinct prophetic or foretelling strain running throughout. The father of John the Baptist is told of his son's birth; and Mary, of the unusual birth of her divine Son. The disciples are told of the coming of the Holy Spirit. And Agabus tells of a great famine coming. In these instances the fulfilment follows soon after the event is foretold. The destruction of Jerusalem, foretold by Christ, had at least a part of its fulfilment in the terrible Titus siege of 70 A.D. Our Lord said that He would return to earth in great glory, and that there would come a great tribulation to all the earth, and repeated the old prophecy of a restoration of the Hebrew kingdom. These have not yet occurred. But the book of the Revelation is distinctively the prophetic book of the New Testament. It deals almost entirely with events that are yet to come. It would be natural that it would fit into the prophetic parts of the Old Testament. So that one who is somewhat familiar with the prophetic books of the Old naturally comes more intelligently to this prophetic book of the New. It is true that most of us have a sense of bewilderment about prophecy. We seem to feel that it requires great scholarship and profound study, and that an understanding of it is not possible to the common run of Christians. And so we largely leave it out as not understandable. Yet prophecy is simply God's plans for the future, together with a revelation of other events which are not in His plan, but which He sees will happen in the future. In it He tells us what He means us to understand. And more than this, our understanding will have practical bearing on our attitude toward evil and compromise. It will affect our faith, making it steadier, especially when evil seems triumphant and overbearing. It will make our prayer more intelligent and confident.
