Here are collected forty short devotional readings, each based on man, -- Babylon, the wonders of the river Nile, the mighty temples of Luxor and Karnack, the Colosseum in Rome, the Sun Temples of the Incas, the Acropolis of Athens, the Great Wall, the Fairy Castle in the mountains of India and the rest, one is confronted by the author with the questions ""What happened to these once-proud cultures that their monuments have so crumbled?"" ""What caused their destruction and decay?"". And when the book brings us at last face to face with the towering buildings of New York, as the pattern of the modern city, one is compelled to ask: ""Will this too pass away?"". The author is a German missionary whose travels have taken him around the world. He has seen the wonders of the world with a penetrating eye and that causes him to raise heart-searching questions. One hundred and more illustrations add greatly to the appeal of the book.
