God in the Dark: The Assurance of Faith Beyond a Shadow of Doubt

Rate this book
Do you have significant doubts about God? Are you afraid to doubt, much less admit to anyone that you aren't fully convinced of God's faithfulness? Are you so torn by your questions that life is losing its meaning? This forthright but compassionate book works to tear away the layers of misunderstanding about doubt to reveal not only its dangers but its great value. As author Os Guinness "If ours is an examined faith, we should be unafraid to doubt... There is no believing without some doubting, and believing is all the stronger for understanding and resolving doubt." For those who are unsure of God's trustworthiness―and for those who are in a dark place, wanting to know "Why?" or "How long, O Lord?"― God in the Dark is a must. It puts a human face on the problem of doubt and examines it thoroughly. In a way that will respond to your questions, settle your fears, and strengthen your faith.

So worth the effort!

Os Guinness is one of those writers that I can only read in small sections. However each of the sections if allowed to to e the object of sitting and pondering is very satisfying. Following his thought pattens is at times challenging but well worth it. He leads us over these pages to a deeper understanding both of the waive variety of experiences that can be called “ doubt” and helps us understand their inevitability but also shares ways in which to engage with them an resist their tendency to take over. I know I shall return to this book many times in the future

Excellent book that examines how and why we may doubt our faith. Especially helpful for comforting friends who may be struggling with the why and how long, O Lord. Part 1 and Part 3 are excellent. I wish part 3 maybe had gone a bit more detailed.

Part 2 was informative on seven types of doubt and the root causes.

Bon livre pour orienter notre réflexion par rapport aux sources de nos doutes. C'est aussi un bon outil pour nous aider à formuler et identifier les types de doutes auxquels nous pouvons faire face.

OS Guinness' God in the Dark could have alternatively been titled The Philosophy of Doubt. In it, Guinness engages with grand, philosophical magniloquence 9 different brands of doubt which often characterize man's struggle with the Christian conception of god. Make no mistake; this is a decidedly dense, high-level read. OS Guinness is clearly an accomplished philosopher and fervid Christian, but I found his dense prose to be somewhat of a detriment to the message he intended to convey. High-level prose certainly has its place in works of this kind, but not at the expense of clarity. What's more curious, his literary style seems at odds with the importance of what is discussed. As momentous as Guinness likely deems the subject matter discussed here, it seems accessibility would be assigned greater importance than eloquent prose.

No matter what specific types of doubt one has faced or is currently facing in one's search for the meaning and source of existence, it is likely engaged here. Guinness describes in comprehensive detail doubt arising from faulty conceptions of god, doubt from a stagnation of faith, doubt from unruly emotions and several others. As these doubts are approached from a philosophical perspective, do not expect many real-world scenarios and arguments. Much of the doubt "flavors" are discussed abstractly, which is understandable given the genre, but the work as a whole might not be sufficiently satisfying for someone looking for analysis of specific reasons for doubts.

While the "intelligent design" (or teleological) argument is often the most cogent argument for the atheist, it's the problem of evil that is traditionally the most difficult issue with which theists must contend, present company included. I wasn't fully engaged in the book until the final two chapters when the problem of evil was discussed, albeit cursorily, and doubt arising from waiting and impatience. Indeed, the majority of the book failed to address any of the problems I am most interested in, and I found the final two chapters to easily comprise the greatest substance the book had to offer.

As an impassioned skeptic of theism and Christianity in particular, I found his arguments lacking just as much as others I've encountered. In my view belief in the theistic, personal conceptions of god is the suspension of reason in the form of faith. Faith, as used in the religious sense, is the adherence to a notion that is unsupported by evidence and thus belief cannot be derived through reason.

His battle with the problem of evil within a worldview predicated on an omnibenevolent, omniscient and omnipotent being ends in a stalemate as is so often the case. Guinness advocates a suspension of judgment because we don't have all the facts, with the unstated but obvious assumption that evil must be somehow good. In the face of untold evil, devastation, starvation, sickness and mass extinctions in our evolutionary past, we simply do not have enough information to judge objectively, he asserts.

Ironically, he inserts a quote in the final chapter which I think rather handily undermines his problem of evil argument. It's a quote by Dostoyevsky's Ivan, and its poignancy is undeniable:

"All the knowledge in the world is not worth a child's tears."

I couldn't agree more.

A dear friend has persistently encouraged me to read this for ages (seems like ages, it has not been ages). Tonight I stayed up all night and pushed through, because she’d asked yesterday if I’d started (I've had many sleepless nights of late).

I resisted at first because Os Guinness’s more recent lectures have made me uncomfortable. The definitive western bias he’s expressed in those talks discomfits me—sometimes even wounds me. Everyone he disagrees with seems to become “radical”: radical Islamists, radical leftists, radical gays. It’s a rhetoric of opposition, not invitation, and it leaves me uneasy. But God in the Dark was published in 1996, and reading it now, I can’t help but wonder what might have caused the drift I sense between that writer and the lecturer he later became.

Anyhoo—this book is not a defense of faith so much as a study of its fragility. Guinness treats doubt not as rebellion but as evidence that faith is alive enough to ache. He writes with humility, not arrogant certainty.

His handling of Job is the heart of the book. Guinness resists the easy impulse to justify god’s silence or to rationalize suffering. Instead, he presents Job as the believer’s mirror—the man who keeps praying into the void, who demands an answer and receives only a presence. The speeches from the whirlwind are not explanations but revelations: God never tells Job why he suffers, only who stands with him in it. For Guinness, that shift—from explanation to encounter—is the hinge of mature faith. Job’s restoration, in his reading, comes not from getting his questions answered but from learning that love can outlast the need for answers.

[edit, later reflection, more on Job: Guinness distinguishes between doubt and unbelief, noting that doubt is a wavering between belief and disbelief, while unbelief is a firm rejection. He positions Job's struggle as one of profound doubt, not a rejection of God. Job's faith is not extinguished by his suffering; rather, it is tested and strengthened as he wavers between what he knows of God's character and the harsh reality of his circumstances.

Guinness highlights the integrity of Job's faith. Faced with pain and the theological platitudes of his friends, Job insists on his own innocence. His refusal to accept a simplistic, formulaic link between sin and suffering is a necessary step toward a deeper, more mature faith.

The book of Job illustrates the ultimate limits of human wisdom when it comes to the problem of evil. Job's friends assume that suffering must be punishment for sin, a viewpoint that the book itself discredits. The answer to Job's suffering is not a philosophical solution but a personal encounter with God. Guinness shows that the story does not provide a tidy theological formula but instead demonstrates that human understanding is insufficient to grasp God's ultimate plan.

One of Guinness's most critical points is that during times of suffering, faith must learn to "suspend judgment." Because "what God is doing may be mystery, but who God is is not," Job is forced to trust in the consistent nature of God's character, even when his actions are incomprehensible. For the person in the midst of a "dark night of the soul," the path forward is not a perfect explanation, but renewed faith in God himself.

By examining Job's ordeal, Guinness puts a "human face" on the problem of doubt and suffering. He compassionately explores how Job's intense agony and demands for an explanation are relatable to anyone who has endured inexplicable evil. Through Job, he shows that the wrestling with God is a legitimate part of the faith journey, not a sign of its collapse. Guinness highlights the integrity of Job's faith. Faced with pain and the theological platitudes of his friends, Job insists on his own innocence. His refusal to accept a simplistic, formulaic link between sin and suffering is a necessary step toward a deeper, more mature faith. End late edit, Job is my favorite OT book, and one I have studied for a long time. I think this may be one reason my dear friend has persisted.]

I’ve never been good at prayer. My mind wanders, my words thin out, and too often I give up before I begin. But this book reminded me that the psalms teach those who struggle to pray how to pray—that lament, confusion, and even accusation can still be forms of faithfulness. Psalm 27, 63, and 88 come to mind; I’ve heard him preach on these, though he doesn’t name them here. It also made me think about Quaker silent worship—the way sitting in stillness can feel like both prayer and its failure, as if the silence itself were the only honest thing left to offer. Guinness reminded me that faith isn’t measured by how much we say to God, but by the willingness to keep showing up, even when all we have to bring is quiet.

Reading it now, I’m struck by how tender it feels. The Guinness of this book still believed that truth could afford patience—that grace and intellect could coexist without the armor of cultural defensiveness. His later tone sometimes sounds more western than biblical, more anxious about moral order than open to mercy. But this book stands as a record of a humbler voice—one that dared to let faith breathe inside mystery rather than barricade it behind certainty.

The book has many other strengths as well. Most importantly, he gives biblical remedies to doubt, including examples of how Jesus dealt with doubters. One comparison in particular was especially perceptive. When the leper came to Jesus in Matthew 8, he doubted Jesus’s compassion: “Lord, if you will, you can make me clean” (Matt. 8:2). He doubts not the power of god but the mercy of god. In contrast, the father of the demonized boy in Mark 9 doubts the power of god: “But if you can do anything, have compassion on us” (Mark 9:22). It’s a simple, brilliant observation—doubt has faces, and god meets each differently.

In spirit—the Spirit in me, anyway—God in the Dark belongs beside Dostoevsky’s Crime and Punishment, a book I recently finished (and one my dear friend and I have shared—tried, at least). Both are confrontations with conscience; both ache toward grace. Raskolnikov’s confession and Job’s lament share the same cry: the need to be seen, forgiven, restored. Guinness doesn’t solve that cry—he honors it. That was an important message for me tonight.

In closing, I think this would be a very good book for pastors—and I have to add, Friends—counseling those struggling with doubt.

Five stars—for honesty, for doubt, for faith that survives by trembling.

These are my sleepy thoughts.

The author proposes an analysis of 7 types of doubts that might attack a Christian. I found the chapters often lacked concrete examples and were vague enough to encompass all kinds of experiences, at the expanse of being easy to imagine.
What bothered me most, though, is that nowhere, not a single time, the author acknowledges the slight possibility that maybe, just maybe, his definition of faith, his definition of God, are not actually the truth. Doubt arises from a wrong understanding or a wrong practice of the Christian faith, or from unruly emotions: the fault always lies within the doubter, not with God not actually being there, or the Bible not actually being infallible.
The chapter about doubting the existence of God was far from satisfactory, dismissing it with something like "the reader can find compelling evidence for the Christian God somewhere else, for this book we will just assume the validity of the classic apologetic arguments, and so a Christian can trust in these facts once and for all. Doubt about them merely shows a lack of understanding or a lack of education in answering the question of God, additional research will solve them". Well. That was helpful.

This is not a light subject, but Guinness but a lot of effort and thought into it. His message is clear and easily understood. He comes straight out with some powerful statements such as this one:
“. . . truth is true even if nobody believes it, and falsehood is false even if everybody believes it. That is why truth does not yield to opinion, fashion, numbers, office, or sincerity—it is simply true and that is the end of it.”
Wow! Great job Os! And keep stating it as it is. I really admire folks who are not afraid to risk their reputation by openly communicating potentially offensive statements for the sake of the truth.)
I was able to take a few powerful statements from this book (Including the above one) and quote them in my own book, The Box Top to Life's Puzzle, in which I also recommend God in the Dark as a complementing read.

Os Guinness’ work masterfully encapsulates all types, aspects, and root causes of the doubts that constantly affect the believer. He both gently handles the “bruised reeds” (Matt. 12:20) of believers plagued by doubts, and also lovingly reprimands the once-fiery now passionless Christians who permit doubts to plague them.

The most important aspect of this book is Guiness’ direction for a solution to the doubts. He is practical and truthful, prescribing short-term solutions, but points always to the long-term solution of God’s faithfulness. It is the existence and character of God that are the solution for doubt, and NOT the strength of our faith in Him.

Basically, read this. A great book to commence my Impact 360 Fellows reading list.

Very helpful read. Contrary to the front-cover summary, this book delves way past simply doubting your salvation or doubting there is a God, but attempts to look at all the different causes for doubt to shake both believers and non-Christians, and ways we attempt to mask doubt, or struggle in faith, or judge doubt too harshly. Doubt has been an obstacle in the way for every human on earth in one way or another, and this book not only helps you identify the true cause and nature of specific doubts, sometimes lying underneath actions, but also offers steps to reconcile doubts and strengthen faith.

There are many apologetic books to help whittle away at the doubt of unbelievers or to strengthen the faith of believers, but what about a book for believers dealing with crippling faith? “God in the Dark” is that book. Instead of tiptoeing around this sensitive issue, the author charges ahead with intellectual rigor and brotherly compassion. He engages both the mind and the heart, allowing the reader to see the real picture of doubt—not as something to be ashamed of but as something that, when rightly understood, can strengthen our faith. If you are struggling with doubt about your faith, please read this book. It will be an invaluable resource.

Highly recommended for those whose faith has been shaken by doubt. As I was reading this, I was playing random music, and the song "Love in the Dark" by Adele began playing. The lyrics to the song fit perfectly with the title and theme of this book ... "I can't love you in the dark. It feels like we're oceans apart. There is so much space between us. Maybe we're already defeated ..." This book will get you back on track.

One problem with reading a book over a period of 6 months, is that one forgets most all of what went before, once one gets to the end. Though I can't remember much, I recall the first part of the book as meriting 4 to 5 stars and the middle section, earning itself 1 or 2 stars and the last part of the book calling for 3 or 4 stars.

Sadly, as one dealing with doubt, I don't feel any better off having read it. There is good material here though. Guinness defines what doubt is and then shares what he calls the seven families of doubt. Which are doubt form ingratitude, doubt from a faulty view of God, doubt from weak foundations, doubt from lack of commitment, doubt from lack of growth, doubt from unruly emotions and doubt from hidden conflicts. He finishes off the book with the "Two torturing questions"; why, O Lord (doubt from inquisitiveness) and How long, Oh Lord (doubt from impatience).

Os Guinness doesn't really seem like someone who naturally deals with doubt (of course I know he deals with some, we all do). I could be wrong, but I get the impression his temperament is more geared down certainty. And this is perfectly fine, but it just meant I didn't really Kythe with him. Books like "Oh me of little faith" by Jason Boyett or "Disappointment with God" by Yancey really ministered to the depths of my being, its like we speak the same language angst and doubt and yet somehow we stay Christians. But with Guinness, he seemed like a confident professional and an expert and therefore, I think its a bit hard for us doubters to truly grab on to his words. Though much of what he wrote is true and important, its like we speak a different dialect.

This was like being served a steak on a full stomach. Good stuff - funny timing. I'm full and curiously delighted with simple moments of faith and peace this summer - like a duckling waddling through the shallows. This book articulates aspects of past insecurities I've harbored, let go, and given precious rightside-out meaning. I'm thankful for the many doubts I've troubled myself with over the years (relatively early in my life) because the surprising resolutions provide me with a thick, rhino-like faith. God knows what he's with me doing after all. Sucks, though, when you have divergent thoughts and your feet begin to step on eachother. This is a good book if you're in such a predicament and you're willing to step back and judge yourself.

I really enjoyed this book and found it very insightful and expect to find it very useful in helping others. It was a delight to read for me and I would definitely recommend it.

One minor critique: I did feel that his last chapter on doubts that arise in waiting could have been more helpful in that I found it a little too focused on our need for "visionary faith" and what we can accomplish through it rather than really walking through the real pain of waiting that we all often experience. I found this was a strength throughout most of the book, but a bit lacking in the last chapter.

Nous pouvons croire que nous sommes victimes du doute, qu'il s'insinue dans notre vie à l'improvise, sans nous demander la permission. Et voilà, nous sommes sous son pouvoir. Os Guinness nous démontre que ce n'est pas le cas. Il nous explique clairement sept sources de doute et comment, par une vie spirituelle active, nous saurons nous en prémunir. Il y avait longtemps qu’un livre m’avait captivé à ce point. Je vous le recommande et pas besoin d’être dans le doute pour apprécier son contenu.

"This is an updated version of ""In Two Minds"". The book starts with a discussion about the role of doubt in the life of faith. Doubt isn't the enemy of faith, unbelief is. Doubt relationship to faith/unbelief is like fear in relationship to courage/cowardice. The rest of the book examines seven common roots of doubt."

Os says that sometimes we don't fully believe what we think we believe, and we move on to deeper theology to quickly. That may be part of the reason God is in the Dark for us. He instructs us to go back and examine more fully the very basics of our faith.

Although reading Os Guiness is a difficult task, once I got used to his style of phrasing sentences, I got to understand and enjoy his intellect.

Os thinks that somewhere along our Christian living we all get to doubt and provides us with different methods to handle the doubt that may arise.
