Then there are the lands and nations under the control of those two great mediaeval historic forms of Christianity, the Roman and Greek Churches, in which the vital principles of the Christian life seem to have been almost wholly lost in a network of forms and organization. The essential truths are there. But they are hidden away and covered up. There are untold numbers of true Christians there, but they live in a strangely clouded twilight. The third great group is of lands and peoples under the sway of the Protestant churches. <u>The Needle of the Compass of Need.</u> Let us look a little at these peoples. Where shall we start in? The old rule of the Master's command, and of the early Church's practice, was to begin "at Jerusalem," and keep moving until the outmost limit of the world was reached. I suppose that practically, in service, beginning at Jerusalem means beginning just where you are, and then reaching out to those nearest, and then less near, until you have touched the farthest. But the old Jerusalem rule will make a good geographical rule for us English-speaking people, with an ocean between us, in getting a fresh look at this old world that the Master asks us to carry in our hearts and on our hands. So we'll begin there. The needle of a magnetic compass always points north. The needle of the compass of progress has always pointed west; at least always since the Medo-Persian was the world-power. But it is striking that the compass of the world's <i>need</i> always points its needle toward the east. And so, starting at Jerusalem, we may well turn our faces east as we take our swing around the world to learn its need. It may be a relief to you to know at once that there will not be any statistics in this series of talks. We want instead just now to get broad and general, but distinct, impressions. Statistics are burdensome to most people. They are a good deal of a bugbear to the common crowd of us every-day folks. They are absolutely essential. They are of immense, that is, immeasurable, value. You need to have them at hand where you can easily turn for exact information, as you need it, to refresh your memory. And an increasing amount of it will stick in your memory and guide your thinking and praying. There are easily available, in these days of such remarkable missionary activity, an abundance of fresh statistics, in attractive form. We are greatly indebted to the Student Volunteer Movement and the Young People's Missionary Movement and the Church Societies for the great service they have done in this matter of full fresh information. But the thing of first importance is to get an intelligent thought of the <i>whole world</i>. And then to add steadily to our stock of particular information, as study and prayer and service call for it. It is possible to get a simple grasp of the whole world. And it helps immensely to do it.
