2. If the stamp was made by ourselves it would have no power. The letter bearing the stamp would be returned. So we can do nothing of ourselves. There is no good in us. When I was a little boy I was a stamp-collector, and when we could not find a stamp of the desired nation, there was issued what is called a "facsimile" of the original. It was a "make-believe" stamp. It looked all right in our stamp-book, but it was out of place and worthless on an envelope. It was only a pretender so we must not be contented with appearances only. That is the way hypocrites are made. 3. The stamp in the stamp box is always ready for service, just waiting to start on its journey. It has the mark of approval on it which the Government has given it. It has the sticking power which man has given it, and is just waiting to be called into service. Paul said, "I am now ready" not only to die but to live. He who is ready to die, is best prepared to live. Always ready for service, like a postage-stamp, is to be ready to go anywhere for the Master. 4. The postage-stamp is a good missionary. It will work anywhere. It will go to any part of the homeland or any part of the world, just as it is directed. No dividing-line between home or abroad, It will go to any part of the world. It just goes where it is sent. It is like a pair of bifocal glasses. It can see home needs as well as the far-away needs. It sees both clearly. That is the plan of Jesus, Jerusalem and the uttermost parts--both are alike to him as far as concerns their need of salvation. 5. I remember also that when I was a stamp-collector, I had one page in my book on which I had a stamp from each nation. They were all at peace with each other. It was the first picture of "The League of Nations." To illustrate the truth, get as many stamps of the various nations as you may be able, and fix them on a large cardboard, and show them to the children, or bring them out of the Bible to show that if they are true to God's Word, they will live together in peace. This is the only "League of Nations" that can stand through the ages. 6. The postage-stamp does what it is told to do. It fulfils its task. When it is placed on the envelope, it takes the letter to the address given. That is its business. That is all that is expected of it. It does not seek to know the contents of the letter, but to deliver the letter to the party named. So it is our business to do just as we are told to do by our Good Father. We are not to pry into his will, or seek to know his unrevealed secrets. Our business is to carry his message. We are to speak where God's Book speaks, We are to be silent where the Book is silent. We should all try to do as well as a postage-stamp.
