In every generation, people wrestle with the same core questions: Does God truly exist? Can we trust the Bible? Is there proof that faith is more than just belief? For centuries, answers have been debated, doubted, and defended. In his remarkable book, The Science Behind the Story of Jesus, John Zachary offers a response that goes far beyond words of inspiration—he presents tangible, scientific evidence that God’s Word is true.
Zachary’s work is unique because it focuses on time-based prophecies—biblical predictions that specify exact dates for events centuries in the future. These aren’t vague, symbolic statements; they are precise timelines that can be tested against history. With his expertise in mathematics, astronomy, and logic, Zachary digs deep into the prophecies of Daniel, the Old Testament feasts, and other key texts, uncovering patterns that point undeniably to divine orchestration.
One of the most astonishing findings is his analysis of the 14,000-day control periods that appear repeatedly throughout Scripture. From the days of Moses and Joshua in the 15th century BC to the destruction of Herod’s Temple in AD 70, Zachary shows how history falls exactly into place on these prophetic cycles. By relying on NASA’s lunar data, ancient Babylonian astronomical diaries, and precise calendar conversions, he demonstrates that these events were not random. They unfolded on exact prophetic deadlines, confirming that history is guided by a higher power.
Equally striking is Zachary’s explanation of the connection between Old Testament feast days and New Testament events. For example, Jesus’s crucifixion occurs on Passover, His resurrection on the Feast of First Fruits, and the arrival of the Holy Spirit on Pentecost. These are not coincidences—they are exact fulfillments of patterns set in motion centuries earlier. The consistency is overwhelming, and it deepens the reader’s appreciation for the unity of Scripture.
Zachary also addresses one of the most common stumbling blocks for skeptics: the supposed contradictions between Gospel accounts. His careful analysis of Pharisaical and Sadducean calendars shows that these differences are not contradictions at all, but complementary perspectives shaped by distinct Jewish traditions. Rather than weakening the reliability of the Bible, these details confirm its authenticity and historical accuracy.
Beyond the data, what makes this book especially powerful is its accessibility. Zachary has written it for both the scholar and the everyday reader. Each chapter includes summaries for those who want to grasp the big picture, while the appendices provide meticulous details for those who want to go deeper. And to keep readers engaged, he adds a creative thread called “Tourists from the Future”—a fictional storyline that allows us to imagine what it would be like to witness these prophetic events firsthand. This unique blend of scholarship and storytelling makes the book not only informative but deeply engaging.
The message of The Science Behind the Story of Jesus is clear: faith and science are not enemies. Instead, when carefully examined, science becomes a tool that confirms and strengthens faith. Zachary’s decades of research stand as a testament to this truth. His work is a reminder that God has not left us in the dark—He has embedded evidence of His presence and His plan throughout history, for those willing to look closely.
Final Insight: If you’ve ever struggled with doubt, wondered about prophecy, or longed for solid evidence that faith is rooted in truth, John Zachary’s book will speak directly to you. It proves that the God who authored Scripture also authored the very laws of time, science, and history. And through them, He has left behind undeniable evidence of His eternal truth.
