“Sweeping in scope and teeming with insights, this creative and compelling book shows us the horror of a world without Christianity. An eye-opening work that should be read with pen in hand to mark points to remember. Truly powerful and persuasive.”

Lee Strobel

selling author of The Case for Christ and The Case for Faith

“This brilliant book is a wake-up call to a world that refuses to see the impact of the life, death, and resurrection of Jesus Christ and to a church that has too often forgotten who we are and what we believe.”

Sheila Walsh

co-host, Life Today

“In today’s politically correct environment, Christianity is the militant secularists’ default scapegoat, blamed for every societal problem. A sober review of history into the modern era exposes this calculated effort to demonize Christianity. Unimaginable documents Christianity’s overwhelmingly positive influence on the world and, contrastingly, describes the horror anti-Christian forces have inflicted on mankind. Refreshingly, Johnston corrects the record.”

David Limbaugh

selling author, attorney, and commentator

“A sophisticated, thoughtful book based on a profound assumption–and it entertains as well as instructs.”

Dr. Rodney Stark

Distinguished Professor of the Social Sciences and Co-Director, Institute for Studies of Religion, Baylor University

“Brilliantly conceived and beautifully written, Unimaginable is a splendid book for both Christians and non-Christians. . . . I heartily commend Johnston for this outstanding work.”

David S. Dockery

President, Trinity International University/Trinity Evangelical Divinity School

“For half a century, America has been moving away from its Christian heritage. Many apparently are oblivious to the value of this heritage and how it laid the very foundation on which this great nation was built. I am pleased to recommend this compelling and fascinating book.”

Mike Huckabee

former governor of Arkansas

“This book joins What If Jesus Had Never Been Born? and Who Is This Man? as historical affirmations of the positive effects of the Christian faith. Easy to read and thoroughly documented, Unimaginable shows how the fundamental values humans hold dear are traceable to Christianity. Where we find a rejection of those values we find death, destruction, and despair. Far from being a detriment to the world or the source of all ills, Christianity is foundational to our concepts of freedom, equality, and human dignity.”

Thom S. Rainer

President and CEO, LifeWay Christian Resources

“Much of the way we interpret reality is determined by how we view the world, and the Christian worldview has shaped millions of lives across the globe. If you want to make the case for what you believe as a Christian, or simply want to investigate the truth for yourself, this book will you in a new and meaningful way.”

J. Warner Wallace

cold-case detective, Senior Fellow at the Colson Center for Christian Worldview, and author of Cold-Case Christianity, God’s Crime Scene, and Forensic Faith

“Unimaginable is brimming with hope as the author proves not only the relevance of Christ to culture but also the heart-healing, spirit-restoring power available through the Savior. Bravo!”

Janet Parshall

nationally syndicated talk show host

“A timely, well-researched, and fascinating book . . . the definitive response to the claim that Christianity is ‘poisonous’ for the world.”

Sean McDowell, PhD

Biola University Professor, speaker, and author of fifteen books, including A New Kind of Apologist

“Wow! This book is a FastPass to the epic ride known as the Christian faith . . . a must-read for anyone who wants to ‘give an answer for the hope that lies within us’ (1 Peter 3:15). The author’s scholarly detail encourages parents, students, teachers, and pastors to dig deep.”

Dr. Jay Strack

President and Founder of Student Leadership University

“Western culture is under assault, and it may not survive. That’s why Unimaginable is so critical to this moment in history. I encourage you to share it with someone who thinks the Christian faith is outdated and irrelevant, because what comes after Christianity may be the end of us all.”

Phil Cooke, PhD

filmmaker and author of Unique: Telling Your Story in the Age of Brands and Social Media

“What a difference the gospel makes! The book presents not only a powerful apologetic for a culture that takes for granted the legacy of the Christian faith but also a clear vision of the transforming power the gospel can bring to any society.”

Paul Copan

Pledger Family Chair of Philosophy and Ethics, Palm Beach Atlantic University; coeditor of The Dictionary of Christianity and Science

“Unimaginable contains insights into human history and culture that to my knowledge have not been perceived before. Some of it is simply terrifying. Today’s atheists and nihilists do not know they are playing with fire, a fire that could destroy our civilization. What ended slavery? What ended systemic abuse of children and women? What ended gross ignorance and superstition? Read this book and you will find the answers.”

Craig A. Evans

PhD, DHabil, John Bisagno Distinguished Professor of Christian Origins, Houston Baptist University

“With scholarly research and imaginative flair, Jeremiah Johnston asks us to consider the unimaginable: What if Christianity had not won the war of competing ideologies? What if it were not to continue as a world-changing influence? This insightful book will you to understand why Christianity makes sense for us and the world we live in.”

Justin Brierley

presenter of the Unbelievable radio show and podcast and Senior Editor of Premier Christianitymagazine

“As we live in a world desirous of scourging religion from life, Dr. Johnston shows that without difference-making believers in Jesus, many of the greatest elements of our world would be missing. Atheist, agnostic, or lifelong churchgoer–read this book and realize the importance and power of Christianity.”

Gregg Matte

Pastor, Houston’s First Baptist Church

“A remarkably clear account of the often underestimated impact of Christianity on a culture and on individuals. As an educator, I welcome this engaging text as a primer for anyone interested in the historical, social, and personal effect of the powerful message of Christianity.”

Dr. Carlos Campo

President, Ashland University; Chair of the Hispanic Education Alliance for the National Hispanic Christian Leadership Conference

“Unimaginable is one of those rare books that successfully combines cutting-edge scholarship on the origins of Christianity with meaningful and thought-provoking reflections on the place of religion in the contemporary world. In a bold way, Johnston presents the strong and unflinching case that in terms of ethics, social values, and human equality the world is a better place because of the contributions of Christianity.”

Paul Foster

Professor of New Testament and Early Christianity, School of Divinity, University of Edinburgh

“Someone once asked: What if you woke up tomorrow with only the things you thanked God for today? We tend to take advantage of the stabilizing factors in our lives and communities. If Christianity never existed, what would people miss out on, long for, or worry about? Unimaginable will not only compel you to thank God for his influence but also inspire you to reflect Christ’s heart to a world very much in need of a Savior.”

Susie Larson

talk radio host and author of Your Powerful Prayers

“It is essential that we understand the influence of Christ and the Christian faith upon civilization and culture. Our witness in the world is at stake, and one of the most significant reasons we believe and share our message is the massive impact of Christianity upon the lives of millions. . . . I highly recommend this book.”

Jack Graham

Pastor, Prestonwood Baptist Church

“Jeremiah Johnston takes you on a sweeping ride through history to reveal how Jesus Christ has infused our lives with goodness in ways you may never have imagined. I can’t recommend this book highly enough!”

Frank Turek

Crossexamined.org and co-author of I Don’t Have Enough Faith to Be an Atheist

“Always the scholar who keeps his finger on the pulse of real-world society and culture, Jeremiah Johnston has produced a volume that addresses the myriad of blessings Christianity provides. It immediately reminded me of the ‘New Atheist’ complaints in recent years that religion never produces good results. Read this book and you’ll have more answers than you’ll ever need!”

Gary R. Habermas

Distinguished Research Professor and Chair, Department of Philosophy, Liberty University

“Jeremiah Johnston brilliantly shows us what a world without Christianity has been and would be. I was struck in new ways by just how miserable the lives of most of Christianity’s most famous opponents have been. Don’t be a miserable opponent of Christianity. Read this book.”

Dr. Peter J. Williams

Principal, Tyndale House, Cambridge, UK

“Counterfactual studies are always fascinating, but Unimaginable is especially so. Contemplating a world without Christianity reminds us anew of all the gospel of the Lord Jesus Christ has accomplished and all that his church has done for the world’s good.”

Dr. Jason K. Allen

President, Midwestern Baptist Theological Seminary

“Johnston’s readers have reason to be pleased with his new work that highlights the cultural impact of the Christian faith. Of particular relevance are the sections on eugenics, slavery, and racism, and the historic Christian rejection of these evils. May we take his words to heart in our day.”

Dr. Holly Ordway

faculty, Houston Baptist University; author of Apologetics and the Christian Imagination

“Jeremiah Johnston is one of the brightest young Christian apologists today. Unimaginable will prove to be an invaluable resource for believers who desire to be more effective defenders of the faith. I highly recommend this book.”

Dr. Harold Rawlings

Assistant Director of The Rawlings Foundation

“For the past few decades, Western society has been on a path to purge itself of Christian influence. If the trend continues, will progressives want what they get? Engaging and informative, this timely volume considers what our world and even modern Western society might look like without the tremendously positive impact of Christianity. I love the concept! Christian and non-Christian readers alike will walk away with a conviction similar to that of militant atheist Richard Dawkins: Christianity may very well be the barrier preventing the world from becoming a place where freedom and justice are things of the past.”

Michael R. Licona

PhD, Associate Professor of Theology, Houston Baptist University

“Many say Christianity is outdated and bigoted, based on a book of ancient myths. Jeremiah Johnston beautifully and biblically outlines that from politics to education to the hope of eternal life through Jesus Christ, Christianity is actually the world’s greatest force for good.”

Janet Mefferd

radio host, Janet Mefferd Today and Janet Mefferd Live

“Unimaginable is essential reading. My trusted friend Jeremiah gives us a clear and compelling defense for the positive impact of Christianity on history and society. It is a book that will empower believers and answer skeptics. Read it and share it immediately.”
