Religion has come to be a much stronger force than any material incentives. It is far better at directing positive behaviour towards social betterment than any laws or physical force. For instance, Ghandi and Martin Luther King Jr conducted non-violent protests based upon religious beliefs. Religion can also be used to help bring people together as they are more willing to work together. By contrast, places that reject religion, such as Revolutionary France, communist Russia and China, or Nazi Germany are often very brutally oppressive. However, it is not always the case. For example, Iran: a country where religion is so prevalent is equally as oppressive as these countries.
Incidentally, religion can be very dangerous because it can and has been used to justify horrific acts. Crusaders not only killed many Muslims, they also massacred many Jews and Eastern Christians in the process of attempting to win control of the Holy Land. Adolf Hitler's followers - among them the so-called German Christians - were believers in their Fuhrer. The Inquisition carried out its torture in the name of God. Religion should never be involved in politics because it can then be used as an instrument of control.
However, in places where religion develops freely and people have free access to places of worship, it provides people with a sense of hope, praying serves as therapy and members of a congregation feel a sense of community and friendship. Some of the greatest works of art were created in the name of God. Furthermore, Woodrow Wilson suggested that a strong affinity exists between religious commitment and patriotism. Love of country,
