The 20th century was one of superlatives, both good and bad. The invention of the airplane, the landing on the moon and the advances in medicine, communication, and in almost every field of science were breathtaking. People today live longer, healthier and more productive and secure lives than ever before. Unfortunately, the utter devastation of modern warfare, the oppression and murder of millions, and the falling away of whole cultures from the truths of God are also breathtaking. People live under the constant shadow of mass destruction and a lonely, materialistic worldview that drains the humanity out of man.
