Book Review: “God’s Crime Scene” by J. Warner Wallace

gcs-wallaceJ. Warner Wallace is the a homicide detective and the author of Cold Case Christianity, one of my favorite introductory apologetics books (see my review). He recently came out with his second apologetics book, God’s Crime Scene. The former work focuses on the evidence for the resurrection and the reliability of the New Testament. In God’s Crime Scene, Wallace makes a convincing case presenting evidence for the existence of God.

The first question I think readers will ask is: “What separates this introductory apologetics book from the pack?”

That’s a valid question. There really are a rather large number of intro-to-apologetics books on the market now (thank goodness!). God’s Crime Scene is different from the rest in that it makes real-world examples central to the case that is made therein. That is, Wallace uses examples of crime scenes that he has experienced throughout the book (sans much of the gory details) to set the stage for each exploration of a different argument for the existence of God.

The way this works is simple: each chapter begins with a story that reads much like a mystery novel. Then, Wallace asks a question like “How might we figure out the evidence inside the room with the victim?” After he presents an answer to that question, he shows how similar evidence inside our own “room” (the universe) points to a being outside the room (aka a transcendent being) as the explanation. This makes the book eminently readable while also being almost immediately applicable.

The arguments that Wallace surveys are the cosmological argument, the fine-tuning argument. an argument from the origin of life, a biological design argument, the argument from consciousness, the argument from free will, and the moral argument. Then, he examines the problem of evil before summing up the case. Each chapter presents a look at the evidence, non-theistic explanations (with critiques), and an argument for why a theistic explanation is superior. The chapters then end with what this evidence tells us about God.

Wallace does a great job summing up many of the arguments involved in some of the standard theistic proofs. Each is analyzed briefly, but with a sometimes astonishing amount of information packed into a tight space. Thus, careful reading is required, and the benefit from a careful read is immense.

There are many illustrations and sidebars found throughout the book. These illustrations are always helpful rather than distracting, and highlight key parts of the arguments that Wallace makes. The sidebars are often discussions of how to weigh evidence according to the U.S. Criminal Justice system or Expert Witnesses that are either for or against the presented argument (this latter point is worth highlighting: Wallace does not only appeal to those with whom he agrees–he fairly presents the opposition’s viewpoint and even references their works directly).

There are a few criticisms I would offer. The first is that it seems like some conclusions are reached rather hurriedly, which is addressed in part through the excellent appendices that add more detail to the cases. Even there, however, one gets a sense that the sheer volume of material to cover is at times a stretch, with some objections only given two or so sentences as rebuttals. The other, admittedly nitpicky issue is that it does seem a little bit weird to have the analogue of the criminal being God. That is, the analogy being used is that just like we can detect a criminal through investigation of a murder scene, so to could we detect God through investigation of the universe. It just seems a little weird. It works; but it’s worth mentioning.

God’s Crime Scene is a valuable resource for those interested in apologetics. The way it is written makes it exciting rather than a chore, and the huge amount of information and argumentation contained therein is well worth the price of entry. I highly recommend it.

The Good

+Great use of criminal investigations to highlight points
+Clear exposition of arguments
+Good illustrations that add to what is written
+Real-world situations increase possibility of retaining information
+Includes experts who are not only theists but also anti-theists

The Bad

-Conclusions at times feel rushed
-A bit weird to have analogue of criminal as God

The Moral Argument: Mistakes to Avoid and Practical Advice

The moral argument has experienced a resurgence of discussion and popularity of late. Some of this may be due to the increased popularity of apologetics. Philosophical discussions about metaethics also seem to have contributed to the discussions about the moral argument. Regardless, the argument, in its many and varied forms, has regained some of the spotlight in the arena of argumentation between theism and atheism. [See Glenn Peoples’ post on the topic for more historical background.]

That said, it is an unfortunate truth that many misunderstandings of the argument are perpetuated. Before turning to these, however, I’ll lay out a basic version of the argument:

P1: If there are objective moral values, then God exists.

P2: There are objective moral values.

Conclusion: Therefore, God exists.

It is not my purpose here to offer a comprehensive defense of the argument. Instead, I seek to lay out some objections to it along with some responses. I also hope to caution my fellow theists against making certain errors as they put the argument forward.


Objection 1: Objective moral values can’t exist, because there are possible worlds in which there are no agents.

The objection has been raised by comments on my site (see the comment from “SERIOUSLY?” here), but I’ve also heard it in person. Basically, the objection goes: Imagine a world in which all that existed was a rock. There would clearly be no morality in such a universe, which means that P2 must be false. Why? Because in order for there to be objective moral values, those values must be true in all possible worlds. But the world we just imagined has no morality, therefore there are no objective moral values!

The objection as outlined in italics above is just a more nuanced form of this type of argument. What is wrong with it? At the most basic level, the theist could object to the thought experiment. According to classical theism, God is a necessary being, so in every possible world, God exists. Thus, for any possible world, God exists. Thus, to say “imagine a world in which just a rock exists” begs the question against theism from the start.

But there is a more fundamental problem with this objection. Namely, the one making this objection has confused the existence of objective morals with their obtaining in a universe. In other words, it may be true that moral truths are never “activated” or never used as a judgment in a world in which only a rock exists, but that doesn’t mean such truths do not exist in that universe.

To see how this is true, consider a parallel situation. The statement “2+2=4” is a paradigm statement for a necessary truth. Whether in this world or in any other world, it will be the case that when we add two and two, we get four. Now consider again a world in which all that exists is a rock. In fact, take it back a step further and say that all that exists is the most basic particle possible–it is indivisible and as simple as physically possible. In this universe, just one thing exists. The truth, “2+2=4” therefore never will obtain in such a world. But does that mean “2+2=4” is false or doesn’t exist in this world? Absolutely not. The truth is a necessary truth, and so regardless of whether there are enough objects in existence to allow it to obtain does not effect its truth value.

Similarly, if objective moral values exist, then it does not matter whether or not they obtain. They are true in every possible world, regardless of whether or not there are agents.

Objection 2: Euthyphro Dilemma- If things are good because God commands them, ‘morality’ is arbitrary. If God commands things because they are good, the standard of good is outside of God. This undermines the moral argument because it calls into question P1.

Here my response to the objection would be more like a deflection. This objection only serves as an attack on divine command theory mixed with a view of God which is not like that of classical theism. Thus, there are two immediate responses the theist can offer.

First, the theist can ascribe to a metaethical theory other than divine command ethics. For example, one might adhere to a modified virtue theory or perhaps something like divine motivation theory. Further, one could integrate divine command ethics into a different metaethic in order to preserve the driving force of divine commands in theistic metaethics while removing the difficulties of basing one’s whole system upon commands. In this way, one could simply defeat the dilemma head-on, by showing there is a third option the theist can consistently embrace.

Second, one could point out that the dilemma doesn’t actually challenge P1 at all. All it challenges is the grounds for objective morals. Certainly, if the theist embraced the horn of the dilemma in which that which is “good” is grounded outside of God, there would be a problem, but very few theists do this (and for them it seems unlikely the moral argument would be convincing). If the theist embraces the other horn–that what God commands is good/arbitrary–then that would not defeat objective morals anyway, because one could hold that even were God’s decisions arbitrary, they were still binding in all possible worlds. While this would be a bit unorthodox, it would undermine the concern that the Euthyphro dilemma serves to defeat P1. Combined with the first point, it seems this dilemma offers little to concern the theist.

All morality is relative

I prefer Greg Koukl’s tongue-in-cheek response to this type of argument: steal their stereo! If someone really argues that there is no such thing as right and wrong, test them on it! Don’t literally steal their things, but do point out inconsistencies. Everyone thinks there are things that are wrong in the world and should be prevented. If someone continues to press that these are merely illusory ideas–that things like rape, domestic abuse, murder, slavery, genocide are in fact amoral (without any moral status)–then one may simply point out the next time they complain about a moral situation. Such is the thrust of Koukl’s remark–everyone will object if you steal their stereo. Why? Because it is wrong, and we know it.

Advice to other Christians

The moral argument brings up some extremely complex metaethical discourse. While it is, in my opinion, one of the best tools in the apologist’s kit for talking to the average nonbeliever/believer to share reasons to believe, one should familiarize oneself with the complexities facing a fuller defense of the argument so they do not come up empty on a question or objection someone might raise. As always, do not be afraid to acknowledge a great question. For example, one might reply to something one hasn’t researched enough to feel comfortable answering by saying: “Great question! That’s one I haven’t thought about. Could I get back to you in a few days?”

As with any philosophical topic, the more one researches, the more questions will arise, the more interesting branches in the path one will approach, and the more one realizes that philosophy is an astoundingly complex topic. For those theists who wish to use the moral argument, I suggest doing so with a courteous, humble manner. The argument is an attempt to answer some of the hardest questions facing anyone: does God exist? is God good? what does it mean for something to be good? do objective morals exist?

Thus, theists using this argument should be prepared for some serious study. Be ready to answer some hard questions. Be open to great discussion. Above all, always have a reason.

The Case for Christianity in 15 Minutes (or less)

Recently, the need for defending Christianity in a short time period has come to light. I was in a discussion with some acquaintances and was asked to outline why I believe what I believe, but we were on a time crunch so I only had about 15 minutes. Thankfully, I have had access to some wonderful resources that allowed me to memorize some quick, but useful arguments.

This post is intended to provide other Christians with a case for their beliefs that they can memorize and share with others. Note that the study cannot stop here. Most people will not be convinced by the basics outlined here. The goal of this post is to provide a springboard for discussion and keep people engaged in  the idea that God exists and Jesus is Lord. Each section is intended to flow directly into the next. I encourage my fellow Christians to memorize a “case for faith” in a manner like this, so they may be prepared with a reason for the hope within them (1 Peter 3:15).

The arguments are necessarily short and simple due to time constraints, but they offer a short defense that will, hopefully, spur further conversation (again, don’t forget to do more research!). Greg Koukl says we don’t need to convince someone right away–we just need to “put a rock in their shoe” so that we can keep the discussion going later. As always, the most effective apologetic is a prayerful, Christ-reflecting life. May the Holy Spirit guide you all.

1. God Exists (7 minutes)

There are many reasons to believe God exists, let me share a few:

Kalam Cosmological Argument

1) Everything that began to exist has a cause

2) The universe Began to exist

3) Therefore the universe has a cause.

It seems intuitively obvious that 1) is true. Things don’t just pop into and out of existence. 2) follows from modern scientific discoveries like the Big Bang, which implies a single cosmological beginning. 3) follows via modus ponens (the most basic form of argument) from 1 and 2. This argument shows a transcendent cause of the universe. The cause must also be personal because [it] brought the universe into existence at some point, which requires a choice. Choices can only be made by persons, so this entity is personal. (See William Lane Craig in “On Guard”, linked below, for more.)

[For more reading on the Kalam Cosmological Argument see my posts linked below.]

The Moral Argument

4) If there are objective moral values, then God exists

5) There are objective moral values

6) Therefore, God exists.

“Objective moral values” here means that moral values are true regardless of what anyone thinks. For example, “murder is wrong” would be wrong even if every single human being thought murder was the way to achieve greatest happiness and encouraged it as an extracurricular activity for teenagers. But the only way to hold that objective moral values exist is to grant God’s existence, because objective laws require an objective lawgiver.

Without God, however, morals reduce to “I don’t like that.” It seems ludicrous to believe that murder is wrong just because we don’t like it. It is something actually wrong about murder that makes it wrong. That which makes it wrong is, again, the commands of the Lawgiver: God. People have a sense of moral objectivity built into them, which also suggests both the existence of objective morals and a God who created in us this conscience. (See Craig “On Guard” and C.S. Lewis, “Mere Christianity”.)

2. Christianity is Unique (3 minutes)

Religions are not all the same:

1) Many religions have contradictory truth claims. (Some forms of Buddhism say: There is no God; Christianity argues: There is a God; Hinduism states: there are many gods)

2) Even among theistic religions, there are contradictory claims (Christianity: Jesus is God; Judaism: Jesus is not God; Islam: Mohammed is prophet; Christianity: Mohammed is not a prophet; Judaism: Mohammed is not a prophet; Islam: Jesus is not God; etc.).

3) The Law of Noncontradiction (actual contradictions like “square circles” or “married bachelors” cannot exist and are not real) shows us that therefore, these religions cannot all be true.

4) Christianity is unique in that  its central religious claim is a historical one: that the person Jesus Christ died and rose again from the dead. This is a historical event which can be investigated just like any other historical event. Yet exploration of this event leads to the conclusion that…

3. Jesus is God (5 minutes)

1) The Gospels are reliable. They demonstrate many criteria for historical truth: multiple attestation (four Gospels telling the same story, but with enough significant differences to demonstrate they didn’t copy off each other), principle of embarrassment (the authors of the Gospels included details which would be embarrassing either to themselves or culturally, such as the fact that women were the first witnesses to the risen Christ in a culture in which women were not trusted), the writers died for their belief in the historical events (while many religious believers die for their beliefs, it seems unfathomable that the Christian Gospel writers would willingly die gruesome deaths for things they made up–which is what alternative theories argue), etc. (See Strobel, “Case for Christ”)

2) Jesus made divine claims “I and the Father are one” John 10:30; “Before Abraham was, I am” John 8:58; etc.

3) The miracle of the resurrection is God’s confirmation of Jesus’ divine claims. If the Gospels are reliable (per 1), then Jesus is divine.


There is good evidence to think that God exists. There are even other arguments that could be presented, such as the teleological, ontological, transcendental, argument from religious experience, and more. We can also see that not all religions can be true. Furthermore, there are good reasons to think the Gospels are reliable and that Jesus claimed to be God and had His claims authenticated by God Himself in Jesus’ resurrection.

Remember, this is not even close to a full defense of Christianity. It is simply a condensed, easy to remember defense designed to be ready at a moment’s notice for when the Holy Spirit leads people into our paths. We need to do more research, offer more arguments, and continue to witness as the Holy Spirit works through our testimony. This defense is by no means a total apologetic; it is meant only as an introduction to spur further conversation. Always have a reason.

Later Edit:

Some have objected to this post on various grounds, most of which are reducible to my arguments not being developed enough. I emphasize once more, this is supposed to be used for a 15-minute defense of the faith, not an entire survey of the field. See my links for more reading, and continue to investigate for yourself.

Further Reading

If you are interested in further reading on these topics, I suggest:

1) On my site, check out the posts on the existence of God: here. Specifically, for the Kalam Cosmological argument:

The Kalam Cosmological Argument

Dawkins and Oppy vs. Theism: Defending the Kalam Cosmological Argument

“The Multiverse Created Itself” and “Who made God after all?”- The Kalam Cosmological Argument

The Leibnizian Cosmological Argument (not developed in this post).

2) On Guard by William Lane Craig- a basic level introduction to many of the ideas discussed here.

3) The Case for Christ by Lee Strobel-a wonderful book which goes through many issues of historical Christianity. Presents evidence for the historicity of the Gospels and the divinity of Jesus.

4) Mere Christianity by C.S. Lewis-a Christian classic, this work is a fantastic defense of Christianity. C.S. Lewis is a masterful writer and I highly recommend this work.
