Who is God? What is God? Did God create man or did man create the idea of God? Is there one God for all religions? If God exists, why does he allow so much suffering? If God is love, why do so many of his followers fight in his name?

These questions of the millennia inspired director Peter Rodger, as chronicled in the documentary “Oh My God,” to visit the world’s seven continents in search of answers.

One might expect that such a journey would lead Rodger to the most devout adherents of the world’s religions; but he leaves no stone unturned, conducting dozens of interviews with businessmen, actors, musicians, humanitarians, aborigines, monks, militants, human behavioral specialists, illusionists, the sick and maimed, homeless people, and natural disaster victims. Of those subjects, you might be surprised to learn who’s who in this global collection of atheists, Muslims, Hindus, Buddhists, Jews, Christians, Catholics and so many others.

Up-close-and-personal interviews give the film an intimate feel, while breathtaking vistas might cause some to question how life as we know it could exist without the guiding hand of a higher power.

All of the material is handled gently, with Rodger careful not to shove any particular concepts down his audience’s throat. He paces the film in such a way that all of the thought-provoking ideas presented will either draw you closer to your faith, or cause you to leave the theater questioning everything you know.

Most often, God is referred to as love or peace — the one from whom all good things flow. These concepts are not new, yet they are essential to illuminating the perspectives that drive millions, if not billions, of believers. These beliefs, as humanitarian and musician Sir Bob Geldof puts it, “are the basis for entirely successful cultures.”

Naturally, the common threads running through all faiths causes many to wonder why such conflict exists between them. The answer is not an easy one; however, Rodger elicits a number of intriguing theories.

Indian philosopher Chhote Bharany suggests that the human “ego” causes such upheaval, while others explain that humans are hard-wired to battle for territory and rights to the “one true God.” Still others believe there is a lack of knowledge among religious believers, who either misinterpret God’s word or are misled by leaders who use them to carry out their own ill intentions. Another suggests that “perhaps God is a way to give validity to a bunch of lost souls who wish to belong to something.”

Tapping into what may be uncharted territory, John F. Demartini, a human behavioral specialist, explains in the film that “we tend to project our image and imagine God to have a sensory function and a motor function like we do so we can communicate and have a personal relationship,” he said. “And we tend to project onto God those things that support our values instead of those things that challenge our values … The truth is, the opponent is yourself, and when you finally embrace yourself, you love people.”

The questions are plenty and the responses are many, but that is the beauty of the film: We are left to decide.
