Morgan Freeman has been the voice of God. Now he will be the face of a series that explores our quest to understand the divine.

Freeman, who has frequently shared his own opinions on the subject, will host and exec produce Nat Geo’s “The Story of God.”

“The story of God is one of the greatest mysteries and most important ideas in the world,” said Freeman. “For me, this is a personal and enduring quest to understand the divine, and I am humbled by the opportunity to take viewers along on this incredible journey.”

Described as an “epic adventure and profoundly personal journey into the eternal mysteries of the divine,” the series will follow Freeman as he embarks on an epic exploration and intimate reflection on God, immersing himself in religious experiences and rituals all around the world, as well as becoming a test subject in scientific labs to examine how the frontiers of neuroscience and cosmology are intersecting the traditional domain of religion.

“God is arguably the most important topic of our time,” said Lori McCreary, Freeman’s producing partner at Revelations Entertainment and an executive producer on the series. “National Geographic’s unprecedented inside access will allow us to explore the global mystery behind God and religion. With Morgan as our storyteller, we’re going to produce a visually stunning and thought-provoking series that will spur meaningful conversations about God and faith, by believers and nonbelievers alike.”

The series will also include Freeman’s own opinions on the matter, as he ponders and shares his personal reflections from the back of a taxi leaving the Vatican or hiking through the Guatemalan jungle on the way to an abandoned Mayan temple.

“We’re partnering with Revelations Entertainment and the talented, multifaceted Morgan Freeman to produce an epic and very personal journey to understand mankind’s religious devotion,” said Courteney Monroe, CEO, National Geographic Channels. “Blending science, history, anthropology and personal experience, we’re harnessing the power of the National Geographic brand and our unparalleled global reach to tell a meaningful and awe-inspiring story of religion and spirituality, across disciplines and faiths.”

“The Story of God” will be produced by Revelations Entertainment for National Geographic Channel. For Revelations Entertainment, Freeman, McCreary and James Younger are executive producers. For National Geographic Channel, Michael J. Miller is executive producer; Kevin Mohs is vice president, production and development; Alan Eyres is senior vice president, programming and development; and Tim Pastore is president, original programming & production.

“The Story of God” is slated to air in 2016 on National Geographic Channel and Nat Geo Mundo in the U.S. and globally in 171 countries and 45 languages.
