Forensic Faith

Forensic Faith: A Homicide Detective Makes the Case for a More Reasonable, Evidential Christian Faith (David C. Cook, May 2017)

A cold-case detective helps you rethink and share your Christian beliefs.

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

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.

  • I really like the way J. Warner Wallace writes. He is great with analogies and breaking things down for people to understand. I also enjoyed the graphics throughout the book that served as great visual aids for greater understanding. He’s not kidding when he said he was an artist which gifting he did employed as a youth pastor. I also thought it was neat to see various Forensic faith sidebars

  • Intelmin says:

    Forensic Faith by J. Warner Wallace is a book I highly recommend. In an age where we need more than ever to understand what we believe and more importantly, to be able to coherently and cogently declare the glorious message of the gospel, this book will serve as an excellent field manual for defending the faith.

  • Apologetics, knowing how to defend our faith, might seem like a boring subject. Wallace makes it interesting by combining it with his own cold case investigations. I like how he explains how we can gather evidence, evaluate it, draw conclusions and then share it with others. I highly recommend this book to Christians who want a good strategy for knowing what they believe and why.

  • One thing I really appreciate about this book is that Wallace isn’t just telling readers what to do but also how to do it. Everything is laid out in a logical manner, yet the writing is also very interesting. There’s also a very helpful list of resources at the end of the book, as well as a list of questions (in the “Targeted Training” chapter) to help the reader get an idea of where he/she stands as a “Christian Case-Maker.”

  • This book is great! I love that this book is apologetics with a different twist, since it is written by a homicide detective. I love how the book is set up and that it shows just how important it is to be able to know how to present our case for Christianity. This would make a great gift for a high school age student to read before going out on their own. I highly recommend it!

  • Forensic Faith is a Christian Book that helps us see how we need to learn evidence on answers about Christian faith. The children really do need to be taught the answers about Christianity and some adults do as well. It’s always nice to have a book that helps us with some of the answers.

  • I found Forensic Faith to be a very interesting read that contained a great deal of information, some of which I have never previously read. An important lesson from this book is when the author is asking the question, “Why are you a believer?” in the preface. He listed several common answers and then explains to us that our answer should be, “I am a Christian because it is true.”

  • If you’ve been a Christian for any length of time, you’ve probably been challenged on each of these at one time or another. Thanks to Wallace’s clear, evidence-based logic, next time it happens I’ll be much better prepared to meet these sorts of challenges kindly but rationally.

  • Forensic Faith is a dynamic resource every Christian should read. . . . As Christians we are fighting a battle and we need to be armed. We are called to bring in the harvest and not merely agree with society because it is easier. Forensic Faith will teach us how to be prepared.

  • If you are looking to better understand and communicate your faith to others then this book is a good tool to add to your reading list. It’s full of faith, truth, and encouragement, as well as upholding Christians to their responsibility of sharing the gospel of Jesus Christ. I think I might have to add more of this author’s work to my shelves!

  • Forensic Faith is an extremely accessible book that’s written in simple language that would be suitable for teenagers as well as adults. I enjoyed Wallace’s hand-drawn illustrations throughout the book as well. This is a great guide for defending and sharing your Christian faith. I highly recommend it to every Christian age teen and up.

  • I can’t recommend this book enough to Christians. This is exactly what should be happening inside our youth programs and churches, not only for our children but for new believers and old believers as well.

  • I love how straight forward the author is in his explanations. He presents the information very clearly and in a method that makes sense. He does not speak down to the reader, yet he makes sure to not skip steps in his explanation.

  • In “Forensic Faith” the author, a cold-case homicide detective, uses the skills that he has learned from years of experience on the force to show us how to defend our faith. So many times we are asked why we believe “this” or how come you do “that” and unfortunately we do not always have the answers. This book gives us helpful ways to learn how to defend our faith and to stand up for what we believe.

  • Forensic Faith by J. Warner Wallace serves the Christian believer and the skeptic alike. Detective Wallace trains and equips the believer to be a Christian case maker to reach the skeptic. In a day and age where young people are asking questions and considering leaving the faith, this resource by J. Warner Wallace prepares us to take on the challenge.

  • It was fascinating to see how he used strategies for police investigations when investigating the Christian faith and showed us how to do it, too. Wallace has a very timely argument as our culture is becoming increasingly hostile and questioning our faith, sometimes with very difficult questions we can’t answer unless we’ve studied up on the topic. I think it’s especially good for parents and those who work with youth as so many young people are leaving their faith behind in college when they come up against tough questions they don’t have answers for.

  • Forensic Faith makes the case for why you (yes, you!) need to be able to articulate the case for Christianity.

    This book reads just like Cold-Case Christianity in its style. Easy-to-read and easy-to-understand, with lots of examples from Warner’s work as a Cold Case Detective.

  • Forensic Faith inspired me. It was such an encouraging book with lots of tips and suggestions for how to increase one’s faith in an evidential way that will lend itself well to leading others to explore their own faith in God.

  • If you are skeptical about apologetics for any reason, I encourage you to give J. Warner Wallace a chance to change your mind. But be warned—if you read Forensic Faith, you may be hooked!

  • Forensic Faith is the third book of a trilogy with the other two being God’s Crime Scene and Cold Case-Christianity. The author’s heart is to equip Christians with the ability to know and defend their faith with the multitude of evidence available to all. The author was an atheist most of his life and a cold-case homicide detective who has taken the tools of his trade and applied them to Christianity.

  • Forensic Faith is the “why/how” counterpoint to The Case for Christ’s “what”/data. You will find encouragement in your faith walk and, likely, more confidence and willingness to share your testimony and faith publicly. The experts say the best stories are those we are passionate about. Are you passionate about your faith? Do you pursue it and truly love God with all your mind?

  • This is one of the most unique books I have read and reviewed. One of my first thoughts was “what a cool book!” Using his law experience, the author uses investigative methods to investigate Christianity and why we are Christians, and why it is true.

  • I really liked the references to the cold-cases he investigated/solved and then how he tied this forensic process to how we should be examining our faith. All of his points are solid – and important – and copiously backed up with Scripture. Along with all the great information and instruction, the aesthetics of the book make the intellectual discussion feel more conversational.

  • WORD Up! says:

    “Forensic Faith” by J. Warner Wallace is a valuable resource enabling the Christian to deepen their faith by building their case for why they believe what they believe. When we defend our beliefs, we strengthen them and we may also influence the thinking of others.

  • I was excited to see another J. Warner book, this is the third in my collection and it was as good as the previous two. Warner gives us a look into investigating cold cases which highly interests me…lots of insight and information on making the case for Christ. A pleasure to read and an appreciation for what the author has gone through.

  • There’s a special genre to apologetics and you start to realize that certain people’s minds are made up different in the investigative crowd- they just process things different than your average joe. That’s exactly how it was when I read Lee Strobel’s Case for the Creator books and I think Wallace is in the same genre.

  • Noveltea says:

    Wow. I always know when a book should be five stars because I find myself telling pretty much anyone who will listen about the book, and I also want to look the author up and buy any other books they’ve written. That’s totally how it was with “Forensic Faith

  • Wallace writes, most Christians rely on “personal experience, emotional response, and blind faith.” Wallace teaches us how to answer a skeptic or seeker about Jesus Christ. Our answer will not be from “feelings.” The answers Wallace teaches will be from solid case facts to be used “to defend the truth.”

  • J. Warner Wallace absolutely loves young people. Forensic Faith is distinctly a call for church leaders and teachers to adopt an active stance of engagement with apologetics, in order to ground our young people firmly in the faith.

  • In “Forensic Faith”, Wallace teaches us the principles investigators use so we can develop a clear, evidence-based faith. Wallace walks us through devising strategies to master the evidence for Christianity, employing the techniques of a detective and becoming a better communicator.

  • Written in an easy-to-read manner that will be accessible to a wide variety of audiences, “Forensic Faith” is a vitally important book that every Christian should read!

  • Forensic Faith is not only well-written, interesting and informative, I’d say that it is a vital book, especially today. I like that it is thorough, comprehensive and logical – and easy to follow. Wallace has journeyed from atheism to being a passionate, knowledgeable, and clear communicator. Through his creative approach, Wallace makes a compelling case for why our defensive knowledge is important and that Christianity was never intended to rely on “blind” faith – and he’s right.

  • More of Him says:

    This book had so much great information put together in such an interesting and compelling way! I found myself not wanting to put it down because it pulled me in and grabbed my attention from the beginning to end.

  • As Christians, what reason do we give for the hope we have? If you were asked why you are a christian or why you attend church, what would your answer be? Would your answer be based on your experience or your families history within the church?

  • This book was a fascinating and well written, well researched read. Written by a former atheist and homicide detective this book is built up with cold hard facts and gives an absolutely outstanding basis for a fact based faith that can stand up when others ask about the hope that is within you. I loved all of the tips and pointers that he imparted, this book is a must read!

  • This is an excellent book to give you a guideline to help you defend the faith, witness to others and know why you believe what you believe.

  • Mr. Wallace uses his years of experience as a detective and his skills as an investigator to show the value of proving one’s faith. Although, Mr. Wallace uses reasoning techniques that he used as a detective this is not a difficult read.

  • This review is for the book “Forensic Faith” by J. Warner Wallace. This is the second book I have read by Wallace. He is actually a cold-case homicide detective and a former atheist. Wallace uses the skills he has learned as a homicide detective to make the case for the Bible.

  • This is a great books for those of faith. Although readers who are not Christian would also enjoy this read for insight, education, and understanding. For those that are Christian, it can be challenging to have conversations about topics and subtopics that you are unsure of how to answer due to lack of knowledge in that field. This books helps the reader learn how to communicate the truth of Christianity so that others can understand what Christianity is really about. The author talks in a strait-forward and easy to understand manner as though you’re sitting for coffee for the conversation. When I was reading his explanations I would find myself saying “that totally makes sense!”
