I found this book fascinating. As the author points out, most of the “prophesy” concerning the end of the world in 2012 is based on superstition and faulty logic. However, I did get some new information. In the first place there is increased volcanic activity in the world. This could be exceeding dangerous if one of the super volcanoes, like the one in Yellow Stone National Park, blow. The book also points out that increased volcanic activity could be a by-product of increased solar energy entering out atmosphere. The book was worth reading just to discover these facts.
The question of the world ending in 2012, however, remains unresolved. I seriously doubt it is tied to the end of the Mayan calendar, or any other prophesy, either the I Ching, or the Bible. I do believe that the world will end one day for each of us. Whether it ends in a global cataclysm, or as the result of the natural end of our years on earth, we must behave as Christians and be ready for the eventuality. God will be the final judge of what happens to the world. It is our job to be ready whenever that happens.
