Mesa resident Glenn Walling shares his life-changing experience in his debut book “I Met God and Also Satan: The Out-of-Body Experience That Dramatically Changed My Life.”

It is available at Amazon, Barnes & Noble and WestBow Press.

The author examines how he and his college roommate, utilizing the scientific method, tested world-renowned philosopher René Descartes’ theory “I think, therefore I am,” according to a release.

While testing this theory back in his dorm room in southern California, Walling had a life-changing experience he could never have dreamed possible. In the book, Walling shares the details of this other worldly experience, a venture outside of the boundaries of the physical universe, the release states.

“Throughout the text, readers will learn about Walling’s extraordinary encounter and how he faced the most powerful, unearthly principalities, meeting not only God, but Satan as well. Walling presents his story to an atheist professor as they discuss and deliberate the logistics and arguments surrounding what happened and how Walling did not choose to return to the physical world but was sent back,” according to the release.

“I kept the story of this encounter with God and Satan to myself for decades as I was concerned with credibility,” Walling said in the release. “Recently, God directed me to go ahead and write about the encounter and to present answers to logical challenges along with the story presentation.”

“Walling presents a firsthand testimony of God’s existence while using logic to reach a skeptical audience. This thought-provoking book challenges readers to think outside their comfort zone as they read about this factual event in the author’s life,” the release states.

Walling has a bachelor’s degree in mathematics with an emphasis on logic from Point Loma Nazarene University and has completed graduate work in education, business and accounting at Point Loma Nazarene University and San Diego State University.

He spent many years as a teacher at the high school and college level and now is a real estate developer. Walling is a Christian who enjoys baseball and relaxing with friends and family, the release states.
