How To Be Christian

Rate this book
From the revered teacher and bestselling author of such classic Christian works as Mere Christianity and The Screwtape Letters comes a collection that gathers the best of C. S. Lewis’s practical advice on how to embody a Christian life.

The most famous adherent and defender of Christianity in the twentieth century, C. S. Lewis has long influenced our perceptions and understanding of the faith. More than fifty years after his death, Lewis’s arguments remain extraordinarily persuasive because they originate from his deep insights into the Christian life itself. Only an intellectual of such profound faith could form such cogent and compelling reasons for its truth.

How to Be a Christian brings together the best of Lewis’s insights on Christian practice and its expression in our daily lives. Cultivated from his many essays, articles, and letters, as well as his classic works, this illuminating and thought-provoking collection provides practical wisdom and direction Christians can use to nurture their faith and become more devout disciples of Christ.

By provoking readers to more carefully ponder their faith, How to Be a Christian can help readers forge a deeper understanding of their personal beliefs and what is means to be a Christian, and strengthen their profound relationship with God.

Received a copy for review from the publisher.

This was an interesting read. It took me some time to debate between a 3.5 and 4 star rating. I, overall, enjoyed reading this book. However, I was only fond of three of the fifteen chapters in this book. Though I didn't thoroughly love each chapter, I found that I was to be glean some informative points from each chapter.

My favorite chapters were:
- On forgiveness as a necessary practice
- On the appeal and challenges of home life
- On the importance of practicing charity

On forgiveness as a necessary practice
Forgiveness is one of those things that many of us claim we believe in but don't really pursue and live by. I adored this chapter and how much I was able to glean from it. The idea of forgiveness vs excuses really got my attention. Everything in this chapter spoke to me.

On the appeal and challenges of home life
This was by far the realest chapter in the book. It forces you to look at your home life and how much of a Christian you are within your home. Do you show kindness patience and love within your house? Do you care for your family as you do strangers? The reality that there is temptation in the home was amazing to read on. I think many people need to read this!!

On the importance of practicing charity
This chapter was a bit of a wake up call for me. It made me understand that my emotions and feelings have nothing to do with my duty to love people. Liking someone is okay, but whether someone does me wrong or not I am required to love them.

This was a great read. Definitely would recommend it.

*Finished reading for the second time 3rd of Feb, 2024
Not much more to comment on, covered pretty much everything in the first review.


Speaks the truth that being a Christian isn't about being perfect, but getting up after every fall and trying again, to better oneself continually, and rather than judging others, notice the flawed wood of mistakes in your own eye before anyone else's. To be part of a community, 'in the body of Christ', each person is just as important as any other.

It works well as an introduction to Christian theology, probably more so than 'Mere Christianity', as the extracts chosen are more catered for a general introduction and broad ease of access to the concepts of the religion.

CS Lewis's narrative voice is soothing and informative, a bit prosaic and complex due to the time period and reading level, but accessible enough.
The last chapter acts like a Q and A, which is the closest it gets to seeing CS Lewis answering standard and difficult questions on Christianity being asked by the general public at the time and can be beneficial.

I don't agree with everything the man says, but the Narnia creator was a good spokesperson for the religion and a good if not perfect representation of what it has to offer. This collection is a good start and refresher of the aspects of the religion, as well as a way of getting to know more of the man's beliefs and him in general. That is what I believe, anyway.

I’m not satisfied with my detailed notes nor have I read them over xD. If you dare to dive in, quite a task – sadly in length and quality - they’ll be hidden behind the spoiler tag.

Brevity must be its own reward. It’s why Youtube shorts, TikToks, and certain book anthologies exist. The younger audiences might not mind it’s the older generation which might find such a comparison sinful LOL. This is a nice compilation. Feels good to be back in an intellectual sphere. I strayed too far in fantasy/sci-fi drowning myself without realizing it. We’re rekindling some love here, peeps. It’s refreshing.

Lewis’ prose has the everyman’s quality to it while maintaining wit with wisdom. I can’t speak on those who aren’t familiar with Christian beliefs tackling the ideas put forth in this novel. I feel like most Christians, or those familiar with said beliefs, will find several occurrences of reassurance, bolstering of faith, epiphanies, cathartic revelations, and y’know wonder, awe all the rest of the religious jargon. I’m still being sincere. I believe Lewis moved a lot of hearts, this compilation ultimately shows how - CUE TITLE.

In the end now that I’m totally finished with the book I just want to lie in my driveway during cold, quiet nights and watch the night sky for a time. The creation is a miracle. Our participation is just one additional fantastic piece of its beauty and mystery.

This book is a collection of Lewis' essays from various works. The publisher has selected essays around the general theme of practical Christianity. So, this book is not what Lewis would have produced if he had set about the task of writing a book on the practical Christian life. Setting that disappointment aside, we find here a great collection of essays Lewis did write and a transcribed interview of what Lewis did say. So, maybe the next best thing.

Lewis was a great thinker and writer. He had a knack for putting things well. He had a way of taking something very familiar, changing the familiar perspective, and putting it across improvingly. Any mention of Lewis sends certain ones of the population running to fetch their aluminum foil caps to prevent any of Lewis' alien waves from entering their brains. Lewis had his theological problems. He could write a brilliant and beautiful passage and sometimes follow it with a brilliantly ugly passage. Only advertising his shortcomings is to whip a straw horse.

Spurgeon had many critics in his day. They often complained about his girth, the hair on his face, and at least one old lady nearly fainted when she heard something akin to humor in one of his sermons. Those journalists and church marms could always have exercised their personal rights of locomotion and declined to attend Spurgeon's preaching.

Had read a few of the essays before but not all of them.
Particularly liked: On Doubts and the Gift of Faith & On the Christian Art of Attaining Glory.

"To be a Christian means to forgive the inexcusable, because Gd has forgiven the inexcusable in you."

"Our faith in Christ wavers not so much when real arguments come against it as when it looks improbable-when the whole world takes on that desolate look which really tells us much more about the state of our passions...than about reality."

"I do not believe that my desire for Paradise proves that I shall enjoy it, I think it is a pretty good indication that such a thing exists and that some men will."

This is a book for those looking to explore what it means to have faith and be a Christian in today’s society. C.S. Lewis, famous for his Narnia series of books, was one of the great apologists of modern times and his extraordinary skill was being able to communicate otherwise difficult theological concepts in an accessible way to other laymen.

How To Be a Christian collects writings and lectures he made that aren’t already covered in his other famous books like Mere Christianity and The Problem of Pain, which makes it a great addition to those on your bookshelf. Topics covered vary and include: the broad sense of Christian Charity, meaning love for others and the practice of that love; attaining glory (essentially praise from God for the way we live our lives, rather than worldly fame and possessions); and how to live practically as a Christian in the modern world. (Lewis was writing around the time of the Second World War). Essentially, he covered the big issues and answered big questions, which is a core part of the appeal of his essays.

There are certain quotes that I enjoyed that I will try to commit to memory. For example, on acts of Charity, he says: ‘The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of’. I thought this was powerful, like something you would find on a poster.

And also, about the Christian’s view of God’s love for us: ‘He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it’. This is a beautiful reflection and helped enhance my own understanding of God.

At first glance, How to Be a Christian by C.S. Lewis seems like a straightforward guide. However, I quickly realized that this book delves into the complexities that many who deeply identify with Christianity inevitably encounter.

The short answer to “How can one be a Christian?” is that, ultimately, we can’t—at least not perfectly. The only truly good Christian was Christ Himself. Yet, it is in our imitation of Him—imbuing His essence into our soul and continuously striving toward His example—that we come to embody what it means to be Christian.

Lewis also addresses pressing questions that modern believers wrestle with, such as how to reconcile an ever-evolving field like science with an unchanging faith. He argues that the foundation of Christianity does not shift, much like all enduring fields of thought. There are eternal truths—first principles—that remain constant even as our understanding deepens over time. His explanation of this was both compelling and beautifully articulated.

If you seek a deeper understanding of what it means to follow Christ in the modern age, this book provides profound insight. It clarifies what it means to be renewed, to be embraced by the Body of Christ, and to shift one’s focus toward Christ Himself rather than the often rigid religiosity associated with Christianity.

Mesmo após anos sendo uma leitora e tendo contato com diversos tipos de livros diferentes, eu ainda me surpreendo com o poder que os livros têm. E agora percebo que, particularmente, os escritos de C. S. Lewis ressaltam ainda mais essa característica. Lewis sabe exatamente o que escrever e como fazê-lo. E consegue passar sua mensagem de forma clara e objetiva. Sua escrita é de grande impacto!
O autor consegue tocar em pontos sensíveis e bem específicos da fé de uma maneira que nos constrange tamanho seu conhecimento e humildade! O livro me deixou muito pensativa e perplexa também com todo o esclarecimento que traz. Seu conteúdo é exatamente o que o título sugere: um guia de como ter uma vida mais alinhada possível ao cristianismo, mas não de uma forma religiosa e alienada, mas de maneira visceral e sincera. Me arrisco a dizer que, independente de fé ou credo, esse livro é para qualquer um que busque entender a melhor forma de ser um ser humano exemplar. Obviamente o livro vai alcançar seu objetivo total se lido por um cristão.

This is a collection of selected chapters and essays from Lewis's earlier writings, mainly "God in the Dock," "Mere Christianity," and "The Weight of Glory and Other Addresses." The selected material is good but there's nothing new, so if you've read much of Lewis then you'll likely have ready everything in this volume already. It would be an excellent introduction to his writings for someone that isn't already familiar with him.

I would’ve titled this book Musings on Christianity as it is hardly an extensive guide to Christianity. But on my 2nd read through I enjoyed it just as much as the first! What struck me was the accuracy with which he described patterns in mankind that have developed further with the arrival of the Internet: Society’s obsession with the group over the individual, the benefits/pitfalls of political equality, Christianity remaining unchanged despite science and knowledge progressing. Overall a really refreshing read!

Absolutely excepts from previous books but great collection. Mind opening. Love the authors thought patterns, even in the admissions of certain aspects he did not understand in Christianity and he aswell being a learning man inthe faith. On some subject he appeared vague, and look warm. And I agree may not have been equipped enough onthe subject to tuckle it. Christians ought to read, a lot, think and study their Bible thoroughly. It is a standard for a person of faith in Christianity.

I have not read CS Lewis in a while but this which is not really a book but a collection of essays from different writings was very enjoyable. I love Lewis’ use of imagination and analogy to bring his points across, it helps to solidify complex ideas into what these ideas look like in the real world. As with Lewis’ previous books, sometimes his arguments can be hard to follow but I find he writes in such a way that you will always be able to grab hold of something from his essays.

I really enjoyed this book. Each chapter is taken from a section from something of his writings (like Mere Christianity) and they all relate to trying to live as a Christian. I loved certain chapters and I especially enjoyed ones that I had not read the works of yet, because they gave me a fresh perspective

there were excerpts from mere christianity in here and i just read that so i guess those ideas are cemented in my mind now. overall felt a bit less cohesive than that work and certain chapters felt a bit meandering. highlights included the chapter on home life, the one on forgiveness and the one on pointing out faults in others.

How To Be a Christian

C.S. Lewis is a author of stretching your imagination. C.S. Lewis forces you to look deep inside yourself and Speak Truth to Power to ones self. Reading one of his books forces you to read another. My experience with C.S. Lewis is one that reveals, God's Promises vividly into your life.

I'm a bit cynical about these collections because they're not works composed by Lewis. They're snippets of his thought on a subject then packaged together for sale. There are good moments, The Weight of Glory is brilliant, but you can find it in it's full form, not pieces of it. Same with Mere Christianity.

“In the same way a Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after each stumble - because the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out”

Lewis is like eating chocolate compared with much other Christian philosophical writing. It has depth but is quite quickly understandable. It is meaningful and not trite. It is definitely easy to apply to your life. Worth a go🌸

Este livro traz pinceladas de diversos temas relacionados ao Cristianismo, a partir da ótica de C.S. Lewis. É um livro interessante para quem nunca leu nada dele e quer começar. Porém, por ser um apanhado de diversos textos/livros/entrevista de Lewis, nenhum tema é tratado em muita profundidade.

While I did obtain some valuable food for thought in this book, I also have to say that I don't enjoy Lewis's style of writing. Many of his sentences are so long that I'd have to read them more than once to get the appropriate meaning. I prefer concise, shorter sentences.

Excellent edited work

A wonderful collection of essays and interview answers from C.S. Lewis. It doesn't replace reading the entire works they are taken from. As always, he has profound insight into life.
