Colonel John A. Henderson, USAF (ret.) “is a retired Air Force Flight Surgeon and General Surgeon and he and his wife, Ruth live in Asheville, North Carolina. Henderson graduated with honors from the University of Illinois College of Medicine in 1945. He interned at the Research and Educational Hospital, Chicago, Illinois; and was surgical resident at Scott and White Clinic, Temple, Texas. During his Air Force career, he served in England, Spain, and Japan. Within the United States, he was stationed in various states from New York to California.” Colonel John A. Henderson is the author of Fear Faith Fact Fantasy and God.com: A Deity for the New Millennium.  He is also the co-author of Judging God.

According to the book description of Fear Faith Fact Fantasy, “September 11, 2001 shocked the entire world as millions watched airplanes crash into the World Trade Center killing thousands of innocent women, men, children, Jews, Christians, Muslims, Buddhists, and Atheists -- all in the name of god. This barbaric act, carried out in the name of god, caused many people to question the relevance of god in the affairs of man. This book dares the reader to think and reason logically on even the existence of god, let alone its involvement in human affairs. It stresses the harm caused by religions and makes a plea to people to speak up when religion is used to express intolerance, hatred, and bigotry.”

Betty J. Brogaard (author of Dare to Think for Yourself) said of Judging God, “John Henderson and Craig Gurgew pull no punches in their book JUDGING GOD. They fearlessly express the dangers and absurdities of religion in a straightforward manner that will leave fellow unbelievers impressed and glad to be among the freethinkers of this world. Christians and other religionists who read this book may well be angered by it but will be hard pressed to expose concrete fallacies in it. They have only their "faith" on which to fall back.”

According to the book description of God.com: A Deity for the New Millennium, “This book may allow some people to overcome their fear of a vengeful, cruel god that they have been taught to believe in as children. It may allow more people to speak out when they hear religious leaders use their gods to incite people to do harm to other people. It may even allow more of us to admit, “I could be wrong.”
