We are living in an era in which the world is in need of peace, friendship, and solidarity more than ever. The conflicts and tensions which left their mark on the 20th century, are continuing on full speed in this century as well. Innocent people all around the world are suffering because of these conflicts and tensions. Despite the urgent need for solidarity and cooperation, certain circles are inciting conflict, particularly conflict between the world's two greatest and deep-rooted civilizations. This is a problem that should be labored upon. It is apparent that a clash of civilizations as demanded by such people would cause a disaster of epic proportions. One of the best ways of preventing such a disastrous war among civilizations is to strengthen the understanding and cooperation in between these civilizations. This is not a hard task, because there are no fundamental differences in between Islam and the Western world as claimed by certain circles. On the contrary, there are lots of common points in between the Judeo-Christian culture that forms the foundation of the western civilization and Islam. After taking these common features as basis, finding solutions to the problems in the world in cooperation, would not be difficult. The alliance which will be formed in between devout people is a natural result of sincere believers' quest for justice, peace, and their desire to serve humanity. This alliance in between the members of the three religions is not a relation that would be limited with meetings and conferences; it is the unity of devout people who defend common values, who strive for the same goal, who aim to bring solution to common problems. And this unity will be one of the main contributing factors to tranquility at a time when Prophet Jesus' (peace be upon him) second coming is expected and Hazrat Mahdi (pbuh) is present on Earth.
