Cold Case Christianity

Forensic Faith by J. Warner Wallace


Why Are You A Christian?

J. Warner Wallace has asked this question in churches across America over the past several years, and the answer he gets is often disappointing; it’s almost always rooted in some sort of personal, subjective experience. As a community, we Christians aren’t typically prepared to make the case for why we believe Christianity is true from the objective evidence of history, philosophy or science. Worse yet, many of us don’t think we have any obligation to do so.

In J. Warner’s first two books, he made the case for God’s existence (God’s Crime Scene) and the case for Christianity (Cold-Case Christianity). In Forensic Faith, J. Warner completes the trilogy by making the case for… making the case! In Forensic Faith, J. Warner helps readers understand why it’s important to defend what they believe, and provides them with a unique template to help them become effective “Christian Case Makers”. Forensic Faith will help readers:

Understand why they, as Christians, have a duty to defend the truth

Develop a training strategy to master the evidence for Christianity

Learn how to employ the techniques of a detective to discover new insights from God’s Word

Become a better communicators by learning the skills of professional case makers

Forensic Faith is an accessible and exciting call to action. It will help you understand why it’s important to develop an evidential faith as it gives you the tools to accomplish the mission. It will also help you explain the need for apologetics to those who don’t yet understand their duty as Christian Case Makers.


With real-life detective stories, fascinating strategies, and biblical insights, J. Warner hopes to teach readers the daily cold-case investigative disciplines they can apply in their lives as believers. Forensic Faith is an engaging, fresh look at what it means to be a Christian.

    “Now more than ever it’s important to know what you believe and why you believe it. As a Christian in an increasingly skeptical world, we must do more than tell people what the Bible teaches; we must help them understand why they can trust what it says about Jesus. Are you ready to make the case?  Forensic Faith will help you develop a faith that’s dedicated, inquisitive and prepared to answer the tough questions.”

    Andy Stanley

    Senior Pastor of North Point Community Church in Alpharetta, Georgia
    “Today, too many evangelical Christians would rather ‘feel’ their faith than actually understand and defend it. With biblical precision, solid evidence and masterful reasoning, Jim Wallace challenges believers to both embrace and make a thoughtful and intellectually robust case for historic Christianity. Forensic Faith is exactly what the church needs today!”

    Janet Mefferd

    Nationally syndicated Christian radio personality and host of Janet Mefferd Today
    “Charles Malik, famed ambassador to the U.S., rightly quipped, ‘If you win the whole world and lose the mind of the world, you will soon discover that you have not won the world. Indeed, it may turn out that you have actually lost the world.’ In Forensic Faith, Christian apologist J. Warner Wallace underscores the danger of anti-intellectualism and equips you to do something about it.”

    Hank Hanegraaff

    The Bible Answer Man, bestselling author and president of the Christian Research Institute
    “J. Warner Wallace’s Forensic Faith completes the trilogy of wonderful books making the evidentiary case for the historicity and veracity of the Christian faith in language that twenty-first Americans can clearly and readily understand. I have seldom seen an approach to verifying the truth claims of the Christian faith that is more effective than the one taken by ‘God’s police detective,’ J. Warner Wallace. Buy two copies of this book. Read one and keep it, and share one with a lost friend.”

    Dr. Richard Land

    President, Southern Evangelical Seminary
    “Few professions better prepare a person to follow the evidence than being a detective.  And few detectives are better prepared Christians to be apologists than J. Warner Wallace. This book is a classic in how to be a more effective defender of the Christian Faith. I highly recommend it for every Christian, even for those who have given no thought to being an apologist.”

    Dr. Norm Geisler

    Chancellor of Veritas Evangelical Seminary, and author of over 100 books, including Conversational Evangelism
    “Unless you’re one of the three people in America who believe the church is successfully making disciples and winning over the culture, Forensic Faith is a book that you must read and heed NOW!  Detective Wallace shows you how to make a persuasive case for Christianity and why it’s absolutely necessary to do so.  The third book in a brilliant series (Cold Case Christianity, God’s Crime Scene), Forensic Faith is not only insightful and practical, it is beautifully illustrated.  So join the growing movement of case makers to help advance God’s Kingdom by putting this book into practice NOW!”

    Dr. Frank Turek

    Christian apologist, President of CrossExamined Ministries, and author of I Don’t Have Enough Faith to Be An Atheist and Stealing From God
    “Jim Wallace has done us all a service with Forensic Faith.  In these pages, Jim not only makes a great case for the importance of apologetics, but also gives us a thorough and thoughtful method for how to use apologetics in discussing the credibility of the Christian Faith.  As a trained trial attorney and evangelist, I highly recommend Forensic Faith.”

    Abdu Murray

    North American Director of Ravi Zacharias International Ministries and author of Grand Central Question: Answering the Critical Concerns of the Major Worldviews
    “Perhaps, more today than ever, Christians need to be able to defend what they believe and why they believe it, and to do so with passion and proof. In this book, J. Warner Wallace reminds us that the truth is fearless and so should be every true believer.”

    Jack Hibbs

    Senior Pastor of Calvary Chapel Chino Hills and host of Real Life with Jack Hibbs
    “Whether you are an individual looking for where to start answering doubts about Christianity or you are a church community looking to better train and equip your people, Forensic Faith is the practical guide you need. J. Warner Wallace has brought together his intriguing detective stories with practical help for the beginning case-maker. It’s like a reader ‘ride-along’ in a police cruiser, learning the ropes on how to thoughtfully investigate the truth.”

    Mary Jo Sharp

    Assistant Professor of Apologetics, Houston Baptist University and author of Resilient Faith and Why Do You Believe That? A Faith Conversation
    “‘What is truth?’ Pontius Pilot’s question reverberates through the ages to our own skeptical day. J. Warner Wallace challenges you to answer the ‘Pilots ‘of your day with Jesus words, ‘I have come into the world to bear witness to the truth’ and then he equips you to make the case for that truth. More than anyone I have read, Jim trains you to think, prepares you to practice, and encourages you to step out with Forensic Faith.”

    Bill Parkinson

    Founding and “Sageworks” Pastor of Fellowship Bible Church, Little Rock, Arkansas
    “This book connects.  It is one of the most accessible books addressing the foundational issues in apologetics I have ever seen.  Superb material—that every Christian student and leader needs to master—presented in a way that is enormously thoughtful and engaging.  My hope is that churches around the globe read it, study it, and apply it.  It will turn the Church, and then the world, upside down.”

    Craig J. Hazen, Ph.D.

    Founder and Director, Graduate Program in Christian Apologetics, and author of Five Sacred Crossings: A Novel
    “Most apologetics texts introduce the major evidences favoring Christianity. Having completed that task already in two previous volumes, Jim Wallace’s third book in his trilogy, Forensic Faith, is one of only a handful of books that wades into the turbulent waters among the sharks and shows readers how actually to apply the evidences. And why not? As a cold-case homicide detective in Los Angeles for many years and a passionate atheist as well, Jim’s job was to emphasize real-life applications of evidence in the toughest situations. But while applying the same rules used in solving murders, he realized after a long search that Christianity was absolutely true!  Who better to learn apologetic strategies from than one who has spent decades in the trenches? This volume comes highly recommended!”

    Gary R. Habermas

    Distinguished Research Professor & Chair, Philosophy Dept., Liberty University & Theological Seminary and author of The Case for the Resurrection of Jesus
    “Forensic Faith has the kind of unique insight we have come to expect from cold-case detective, J. Warner Wallace. Drawing from skills learned from decades of successfully investigating cold-case homicides, Wallace shows exactly how to go about making a compelling case to Christianity’s critics. This isn’t the “what,” but the “how” – the part most Christians are missing. If you want a practical guide to being a more effective Christian case-maker, Forensic Faith is the book you’re looking for.”

    Melinda Penner

    Executive Director of Stand to Reason, and STR’s senior blogger
    “I didn’t think J. Warner Wallace could top his masterpiece Cold Case Christianity. I was wrong. In Forensic Faith, Wallace gets right to the point. It’s not enough for Christians to believe accidentally; they must know their faith evidentially. But there’s a problem: Many Christians don’t know how to defend the faith. Worse still, many don’t want to know. Theirs ignorance sustained by denial. Wallace graciously, but firmly, says we must do better. Then he masterfully shows us how. Whether you work at Starbucks, drive a truck, or attend school, we are all apologists now. You may be a prosecutor or a defender, but either way, you have a case to make. There is no finer book for getting started.”

    Scott Klusendorf

    President of Life Training Institute and author of The Case for Life: Equipping Christians to Engage the Culture
    “Our Summit students love J. Warner Wallace for the same reason criminals hate him. As one of America’s most well-known cold-case detectives his proven tactics have helped bring the guilty to justice even decades after their crimes. Now Wallace shows how those same detective skills can help you confidently share Christianity’s truth. Forensic Faith is a faith-building page-turner.”

    Jeff Myers, Ph.D.

    President, Summit Ministries
    “In Forensic Faith, Jim Wallace continues his relentless pursuit to transform millions of complacent, unprepared Christians into competent advocates for the truth of the Gospel. This book is for those who are serious about accepting this challenge and doing the hard work necessary to become informed, inspired and involved.”

    Rice Broocks

    Pastor, Founder of Every Nation worldwide family of churches, and author of God’s Not Dead
    “As a former atheist and a police officer, J Warner Wallace understands the importance of evidence — whether it’s the evidence needed to convict a criminal, or the evidence needed to change the heart of a skeptic. In this important new book, Jim offers an impassioned plea for Christians to get a hold of biblical faith—which isn’t blind faith but faith based on evidence: in other words, Forensic Faith. In the increasingly secular and skeptical age we live in, with many (especially young adults) abandoning the Church, it’s vital that Christians don’t just know what we believe, but why we believe it—for there’s only one good reason to believe in Christianity, and that’s if it’s true. Forensic Faith is designed to wake up slumbering Christians, encourage them to get to grips with the life of mind and the reasons why we can be sure Christianity is true—and then, with confidence and conviction, engage their friends and colleagues with the gospel. This is a much needed message in many parts of the Church—and thus I hope that Forensic Faith will help many become passionate Christian case-makers.”

    Andy Bannister

    Christian Apologist at Ravi Zacharias Ministries, and author of The Atheist Who Didn’t Exist: Or the Dreadful Consequences of Bad Arguments
    “I have been waiting for this book for some time. Wallace practically and succinctly makes the case for why every Christian can be a “case maker” for Christ. As a pastor, I know many in my congregation who want to share their faith with non-Christians, but they don’t simply because they do not feel equipped. This is why every church leader needs Forensic Faith. In it, I have found the textbook I have needed for years to help people make the evidential case for the truth of the Christian faith.”

    Scott Luck

    Lead Pastor, Stones Crossing Church, Greenwood, Indiana
    “J. Warner brings renewed energy and duty back to knowing how to give an answer for what we believe. His practical and challenging detective approach challenges every disciple of Jesus to no longer be the “accidental Christian” but to have and a clear and compelling answer. This book will be a great tool for any Christ follower that desires to make a evidential case for why they believe. It’s a call to action for all of us.

    Troy A Murphy

    Pastor of Green Bay Community Church and Chaplain for the Green Bay Packers
    “There are many excellent apologetics books available today, but most Christians still aren’t interested enough in learning to make a case for and defend their faith to read those books—a tragic fact for the church in an increasingly hostile secular world. Forensic Faith is the urgently needed book that boldly speaks to the church at large about this dangerous disconnect. In the same captivating style as Cold-Case Christianity and God’s Crime Scene, Det. Wallace makes the ultimate case for apologetics itself and masterfully lays out a practical guide to help every Christian embrace their calling as a case maker. It’s compelling, concise, and extremely accessible. Forensic Faith is the book I wish I could hand to every Christian today.”

    Natasha Crain

    “In Forensic Faith award winning cold-case detective and bestselling author J. Warner Wallace makes a compelling case for becoming a Christian case maker. Filled with practical advice and powerful evidence, this innovative approach will help everyday Christians learn why they believe and how to share the reason for their hope with others.”

    Dr. Jonathan Morrow

    Director of Creative Strategies at Impact 360 Institute, popular speaker and author of Welcome to College
    “Christians often say ‘You can’t argue people into heaven.’ While that may be true, it’s also true that many people won’t come to Christ until they hear some good arguments! J. Warner Wallace was one of those people—and now, in Forensic Faith, he shows us how to use effective arguments, logic, and evidence to point our friends to the truth of Christianity. This is powerful information from a world class detective, but it’s written for ordinary believers who want to become better case-makers for Christ. I highly recommend it.”

    Mark Mittelberg

    Bestselling author of Confident Faith, Becoming a Contagious Christian (with Bill Hybels), and Today’s Moment of Truth: Devotions to Deepen Your Faith in Christ (with Lee Strobel)
    “J. Warner Wallace is one of the most engaging writers I’ve ever read: to read him is like hearing him argue a public case. It is tragic that we have such strong evidence supporting Christian faith, and yet many church-attending Christians never learn to articulate such evidence for people who–like me in my atheist days–desperately needed to hear it. More tragic still are young minds swayed by the mere assertions of Christianity’s often grossly misinformed, uncritical yet self-assured critics. Wallace’s case for making a case offers a desperately needed correction to a church culture too negligent about articulating truth.”

    Dr. Craig S. Keener

    Professor of New Testament, Asbury Theological Seminary and author of The IVP Bible Background Commentary: New Testament
    “Jim has done it again!  In a masterful way of blending the past with the present and the evidence with the investigation, Forensic Faith not only gives you reasons to believe but tactics to explain it. Unlike many apologetic works, this book weaves in compelling Dateline type stories with real detective skills. This is a must read for all Christians!”

    Rusty George

    Lead Pastor of Real Life Church and author of When You, Then God: 7 Things God Is Waiting to Do In Your Life
    “Jim Warner Wallace is the C.S. Lewis of our times. Forensic Faith is to this generation what Mere Christianity was to its. His blend of apologetics and detective investigation in providing compelling evidence for the Christian faith is exactly what both the world and the church need right now.”

    Joe Amaral

    Host of 100 Huntley Street and author of Understanding Jesus: Cultural Insights into the Words and Deeds of Christ
    “I have been patiently awaiting the completion of Forensic Faith. After J. Warner Wallace’s first two books, I was eager to hear more from The Cold Case Detective. Now I can say, Forensic Faith is excellent, as expected, and I whole-heartedly recommend it! Detective Wallace makes a compelling case for making a compelling case for our faith, so that our faith will be more than accidental, but evidential. As our culture becomes more skeptical of our commitment to our faith, the church must become more and more convinced by the evidence for our faith. Every Christian must know, not only what they believe, but why they believe it. And the evidence is compelling! Thanks again Detective Wallace, for teaching us to think like seasoned investigators in relentless pursuit of, and in confident defense of, Truth.”
