Introduction.As history shows, faith or religious belief can often prove to be a force far stronger than considerations of pure self-interest. In some circumstances, people will even sacrifice their lives for their faith. Whether this powerful force works for the good or for the evil of humanity, it would be a grave error to think that globalization and the economization of thought have diminished the importance of religion. Religion continues to act as one of the main factors in improving human behavior. Man is incurably religious, although the form and object of his religious feelings may change with time. What is religion? Do we need religion? There is no proper definition of world religion because everyone has their own views on religion, but there are few things to consider and understand when we talk about religion. And if there was no true religion, the world would become the darkest prison. What if we weren't told that there are always two paths to spend your life, the right path which is difficult because you have to follow the rules and the law given by the god, and the other path is the easy path where there are no restrictions. no obedience is required. The main philosophy of religion is that it gives us the right way of life, but is there any right religion on earth? Does God exist? What God is like, many other questions arise when we talk about philosophy of religion..
