I was impressed anew with the practical value of this method one day in St. Petersburg. We had gone to look at the panorama of the siege of Sebastopol, then on exhibition in a huge, round building. It will be remembered that the British and French allied themselves with Turkey and Sardinia in an attempt to restrain the encroachments of Russia on Turkish territory. The famous charge of Balaklava, immortalized by Tennyson, is remembered as the most stirring event of that war. Its chief event was the siege of Sebastopol on the Crimea peninsula, in the Black Sea. At the panorama we stood as though on a high central point in the city of Sebastopol, with the view spreading out in all directions. To the north lay the harbour with the Russian ships securely bottled in by the attacking fleets. To the west a body of French soldiers were retreating, hotly pursued by Russian troops, while in the distance British troops are hurrying to the relief of the French. Then we looked east, where the fighting was going on at close range, the wounded being carried away and the reserves hastening up to take their places. And again we turned to the south, where the battle raged fiercest. The face of the commanding officer stood out so vividly. And we almost shrank from the fierceness of the fire. And the smell of powder almost seemed stifling. And as I stood brooding afresh on the horrors of inhuman war, I was tremendously impressed that only by such successive views could I get such a grasp of that memorable siege. I had a more intelligent and vivid understanding of it than ever before. And so it is that we may get a simple, clear, and real grasp of the tremendous tribulation time that is coming, that it is presented to us in this fashion, first one distinct view, then another, and another, till some understanding of the whole begins to get hold of us. We have seen the Lord Jesus, in the vision in chapters four and five, as He comes forward to take an advance step. We have seen the tremendous outburst of praise in heaven as He steps forward. This step and scene are in heaven. The earth is wholly unaware of it _at that moment_. Now all that follows is connected directly with that advance step. This is the significant thing to get clearly fixed in mind. At the present time our Lord Jesus is still walking among the candlestick Churches watching and waiting. We are still in that waiting time. The Holy Spirit still dwells in the Church on earth. At some time in the future, no one knows, nor can know, just when, the Lord Jesus will rise up in readiness for an advance move. He will withdraw the Holy Spirit from the Church up into His presence again "before the throne." _Then in connection with this advance step_ there will occur on the earth the things spoken of in these pages following. This is the tremendous fact to keep clear, the immediate connection between these happenings on earth and His new move in heaven.
