(Preaching) may be slow work; it often is; it is a long-term policy. But my whole contention is that it works, that it pays, and that it is honoured, and must be, because it is God’s own method. This is the thing to which He calls us, it is the thing into which He thrusts us forth, and therefore He will honour it. He has always honoured it, and still honours it in the modern world, and after you have tried these others methods and schemes, and found that they will come to nothing, you will be driven back to this ultimately. This is the method by which churches have always come into being. You see it in the New Testament, and you see it in the subsequent history of the Church, and you can see it in this modern world.
