Religion is the driving force behind much of what happens in the world today -- particularly when it comes to the "big three" religions -- Judaism, Christianity, and Islam. Religious differences have and continue to spark wars, create nations, and spawn ongoing conflict down through the centuries. No matter what religion you adhere to (or even if you claim that you don't adhere to any religion at all), you need to have a basic understanding of the world's religions in order to understand what is happening in the world today so that you can be better informed and a more useful citizen of your nation and of the world. Without some knowledge of religion, you will not understand the underpinnings of what is happening in an increasingly global society.
