Many a time when preaching in the villages of China one has to use very simple illustrations for deep Divine truth. I remember once I took up a small book and put a piece of paper into it, and I said to those very simple ones, `Now look carefully. I take a piece of paper. It has an identity of its own, quite separate from this book. Having no special purpose for it at the moment I put it into the book. Now I do something with the book. I post it to Shanghai. I do not post the paper, but the paper has been put into the book. Then where is the paper? Can the book go to Shanghai and the paper remain here? Can the paper have a separate destiny from the book? No! Where the book goes the paper goes. If I drop the book in the river the paper goes too, and if I quickly take it out again I recover the paper also. Whatever experience the book goes through the paper goes through with it, for it is in the book.' [speaking of being in Christ]
