Editorial Reviews


“In these pages, you’ll learn the most compelling arguments in favor of Christianity. Not only that, but you’ll also find out how to respond to the most popular objections to those arguments. You’ll discover that On Guard is solidly factual, winsomely personal, consistently practical, and ultimately convincing in its presentation of the case for Christianity.”
(Lee Strobel 2010-03-01)

“There is probably no greater defender of the Christian faith alive today than William Lane Craig. On Guard is Craig’s introduction to the wealth of information, logic, and evidence that powerfully point to the truth of our Christian beliefs. Read it to deepen your own faith and to embolden your confidence in sharing that faith with others.”
(Mark Mittelberg 2010-03-01)

On Guard is an excellent summation of how the Christian faith makes sense of the real world in which we all live. ‘Speaking the truth in love,’ once again William Lane Craig proves we don’t have to be abrasive to be persuasive.”
(Jim Thomas 2010-03-01)

“William Lane Craig is arguably one of the finest Christian philosophers of our time. His knowledge and skill have placed him on platforms on every continent, engaging the most notable skeptics in dialogue and debate.”
(Ravi Zacharias 2010-03-01)

“It is hard to overstate the impact that William Lane Craig has had for the cause of Christ. He is simply the finest Christian apologist of the last half century, and his academic work justifies ranking him among the top 1 percent of practicing philosophers in the Western world. Besides that, he is a winsome ambassador for Christ, an exceptional debater, and a man with the heart of an evangelist. I know him well and can say that he lives a life of integrity and lives out what he believes. I do not know of a single thinker who has done more to raise the bar of Christian scholarship in our generation than Craig. He is one of a kind and I thank God for his life and work.”
(J. P. Moreland 2010-03-01)

From the Back Cover

Do you worry that someone will ask you a question about your faith that you can’t answer?

Have you tried to learn how to defend your faith but gotten lost in confusing language and theology?

Do you struggle with times of spiritual doubt yourself?

This concise training manual by renowned scholar William Lane Craig is filled with illustrations, sidebars, and memorizable steps to help you stand your ground and defend your faith with reason and precision. In his engaging style, Dr. Craig offers four arguments for God’s existence, defends the historicity of Jesus’ personal claims and resurrection, addresses the problem of suffering, and shows why religious relativism doesn’t work. Along the way, he shares his own story of following God’s call.

This one-stop, how-to-defend-your-faith manual will equip you to advance faith conversations deliberately, applying straightforward, cool-headed arguments. You will discover not just what you believe, but why you believe—and how being on guard with the truth has the power to change lives forever.

If you've ever desired philosophers to say things in easy to understand, yet not dumbed down language, then you will be pleased with this book.
On Guard seems to take all the great things William Lane Craig says during his debates, podcasts, and interviews, and puts them in one accessible read. For some reason, apologists speak so clearly during their debates, and yet when you buy their book, you get bogged down in technical jargon that keeps you busy either reading the same page 4 times, or rifling your fingers through a copy of Pocket Dictionary of Apologetics & Philosophy of Religion.
Before I got this book, I believed it would be one of those books that would be great for using in a young adults (or not so young adults) Sunday School class, or perhaps giving to someone who knows nothing of apologetics. I was pleasantly surprised to discover that that On Guard is not only that, but also much more! On Guard reminds me of a book that would be the result of an individual's gleanings of the best notes of his studies. (Now I don't have to spend the next year writing all my notes down, because WLC has done it for us! ha ha)

Ok, so now that I've given my impression of the book, allow me to go into greater detail:
On Guard begins with an impressive list of endorsements, ending with the finest by J.P. Moreland, who refers to Craig as, "the finest Christian apologist of the last half century." I wholeheartedly agree, and also place Moreland there too.

We move on to an excellent introduction by Lee Strobel. Lee reminds us of the great debate between Craig and Zindler (a debate I actually paid money to buy on cassette from Moody), and then closes with the claim that, "you'll learn the most compelling arguments in favor of Christianity.

Format: Paperback
William Lane Craig is one of the top Christian apologists alive today. So when he writes a book on apologetics, I expect it to be well-argued and -reasoned. But I do not necessarily expect it to be accessible to the average reader, for better or for worse.

Yet On Guard, released this week by David C. Cook Publishers, is just that and more. This book is ready-made for undergraduate classes, church small groups or any Christian looking for an introduction to the key arguments in defense of Christianity.

Most of the content is not new to the discussion, but the format by which it is presented is. This is one of the primary appeals to this work. There are wide margins on the pages perfect for note-taking, unless that space is used for definitions of key words and logical fallacies. There are even profiles of some of the key thinkers along the way.

Craig presents the chapters in ascending logical order of arguments, from "What difference does it make if God exists?" to "Is Jesus the only way to God?". Along the way he hits some of the most popular arguments today for God's existence: the moral argument, the design argument, and of course the kalam cosmological argument, which Craig is especially well-known for modifying in his doctorate thesis.

If there is one weakness in the book, it is that it tries to be all things to all men. While the book is meant to be introductory, there are points when the content will simply be heavy lifting due to the subject matter at hand--despite the occasional single-panel cartoon thrown in. And the "Talk About It" questions seemingly geared for the small group are, in my humble opinion, more distracting than beneficial.

Maybe it's just me, but I've found the past few years that anti-theists are getting nastier and more nonsensical. The new atheist's philosophical artlessness (plus its gullibility and imbecility) is more than astonishing; it reflects a deep-seated immorality and irrationality. No one has exposed this little secret more than the outstanding public debater William Lane Craig and in "On Guard: Defending Your Faith with Reason and Precision," he equips the average Christian with potent apologetics. This is a "concise training manual" for the non-scholar because it is written in an easy and accessible style. Craig makes classical and evidential apologetics easy to understand as he offers a winning formula for those rationally pre-committed to evidential procedures in obtaining and defending truth.

Recommended by:
- Ravi Zacharias
- Lee Strobel (additionally he wrote the forward)
- Mark Mittelberg
- Jim Thomas
- J.P. Moreland.

This is a resource that is comprehensive enough that the reader need not purchase another evidential book. Craig covers in depth countless subjects that will help train the believer to confidently defend the faith within the bounds of evidentialism.

Topics included within the pages of "On Guard" include"

- What is Apologetics?
- Why does anything at All Exist?
- Why Did the Universe Begin?
- Fine-tuned universe
- Can One be good without God?
- Suffering
- Who was Jesus?
- The Resurrection of Christ
- The exclusivity of Christ
- And much more.
- Bill Craig's apologetic testimony.
The author supplies wonderful charts, graphs, illustrations, small biographies of famous scholars, and "talk about it" questions for the apologetic trainee.
