This book emphasizes the "God" of Christianity. Christians believe that God exists and that He created the world in six days. This book shares this belief, but with an emphasis on God's cunning in the creation of this world in exactly six days, and particularly the creation of many "good and bad things." For example, physical violence among human beings is considered a very negative phenomenon, since the moment Cain killed his brother Abel. This book, however, shows that God made sure that physical violence also has a positive angle, because without violence among humans that God created a significant percentage of them would not be able to afford vital necessities to survive in this world. This example is illustrated with violence in both wars and in the community. The same has happened with natural disasters (e.g., hurricanes, tornadoes); although they are very "bad things" created by God, He also made sure that such disasters could economically benefit an infinite number of people, with the exception of private insurance companies which flatly disagree with God's periodically sending such disasters to this planet. Another example is the cunning of God's creation of the poor and the rich, for it occurred to Him, rightly, that without poverty there is no wealth. According to several verses in the Holy Bible, illnesses are very "bad things" resulting from the violation of God's "divine laws" in the Ten Commandments He sent to Moses when they met on Mount Sinai (a biblical event extensively discussed in the chapter dealing with the "origin of diseases"). This book, however, shows that illnesses could also have a positive angle. The main conclusion in "How God Created the World" is that, if God really created the world in just six days, He created it so perfectly that it is virtually impossible to prove He was wrong.
