For centuries, people have debated whether faith and science can coexist. Many have argued that religion belongs in one corner and science in another, never to meet. But in his groundbreaking book, The Science Behind the Story of Jesus, John Zachary shows us a very different picture—one where faith and science not only meet but strengthen each other.
This book is the product of a lifetime of research. With a background in mathematics, history, and aerospace engineering, Zachary brings a level of precision rarely seen in biblical studies. He applies astronomical data, historical records, and logical reasoning to questions that many thought could never be answered with certainty. The result is a work that bridges the gap between belief and evidence.
Take, for example, his analysis of the 14,000-day control periods found in the Bible. Using Daniel’s prophecies as a foundation, Zachary demonstrates how events such as the decree to rebuild Jerusalem and the destruction of Herod’s Temple fall exactly into place within scientifically calculated timelines. These findings aren’t vague estimates—they are specific dates verified through NASA data and ancient calendars. For skeptics, this is powerful evidence; for believers, it’s deeply affirming.
Another highlight is Zachary’s handling of so-called contradictions in the Gospels. Critics often point to differences between the accounts of Jesus’s crucifixion in Matthew, Mark, Luke, and John. But Zachary’s careful study of Pharisaical and Sadducean calendars reveals that these “contradictions” are actually complementary perspectives shaped by different traditions. Instead of undermining Scripture, these details highlight its authenticity.
What makes The Science Behind the Story of Jesus stand out is not just the depth of the research but the way it’s presented. Zachary structures the book with executive summaries for casual readers and detailed appendices for those who want to dig deeper. And to make the journey engaging, he adds a fictional storyline called “Tourists from the Future,” which places readers right in the middle of the prophetic events.
The takeaway is clear: Christianity does not demand blind faith. Instead, it invites us to explore evidence, logic, and history. John Zachary’s book proves that when we do, the results are astonishing.
Final Reflection: If you’ve ever wrestled with doubts, or if you’ve wondered how biblical prophecy holds up under scientific scrutiny, The Science Behind the Story of Jesus is the book you’ve been waiting for. It will not only answer your questions—it may very well change how you see faith and science forever.
