Let me take you on a journey, my friend—a journey into the mind of C.S. Lewis, a man who didn’t just believe in Christianity but invited skeptics, believers, and wanderers alike to understand it in its simplest, most profound form.
In his timeless work, Mere Christianity, Lewis has a way of making you sit up, take notice, and reconsider everything you thought you knew about faith, morality, and life itself.
So, grab a coffee, pull up a chair, and let me share the most life-changing lessons I’ve drawn from this book.
1. Right and Wrong: A Law Written in Our Hearts
Have you ever wondered why we instinctively know that some actions are just wrong?
Whether it’s cutting in line, lying to a friend, or worse—there’s this inner voice, isn’t there?
Lewis calls this the “Law of Human Nature.”
It’s a moral compass that points to something greater than us.
It’s not just about societal rules. It’s about a divine standard etched into our souls by the Creator Himself.
Romans 2:15 reminds us, “…who show the work of the law written in their hearts, their conscience also bearing witness…”
Friend, doesn’t this realization humble you?
We’re not just physical beings with random ideas about right and wrong.
We are spiritual beings, accountable to the One who gave us this moral law.
2. The Problem Is Us, Not the World
Lewis doesn’t sugarcoat the truth.
He boldly states that the problem isn’t “out there.”
It’s in here—in our hearts.
We want fairness, kindness, and justice from others, yet we fail to meet that standard ourselves.
And here’s the kicker: we can’t fix this on our own.
This is where the gospel shines.
In Lewis’s words, “Christianity tells people to repent and promises them forgiveness.
It therefore has nothing (as far as I know) to say to people who do not know they have done anything to repent of and who do not feel they need any forgiveness.”
How often do we try to justify our failures or blame others?
Yet, Yahshua lovingly calls us to humility: “Come to Me, all you who labor and are heavy laden, and I will give you rest” (Matthew 11:28, NKJV).
3. Christianity Is Hard but Liberating
Lewis says something striking: “Christ says, ‘Give Me all. I don’t want so much of your time and so much of your money and so much of your work: I want You.’”
This isn’t just about attending church or doing “Christian things.”
It’s about surrendering your whole self—your dreams, your desires, your will—to Yahweh.
It’s terrifying, isn’t it?
But it’s also the most liberating thing you’ll ever do.
When we let go of control, we finally begin to experience the life Yahweh designed for us.
As Paul says, “I have been crucified with Christ; it is no longer I who live, but Christ lives in me” (Galatians 2:20, NKJV).
4. True Faith Leads to Transformation
Faith isn’t passive.
Lewis describes it as a living, breathing force that changes you from the inside out.
He uses a beautiful analogy: imagine yourself as a living house.
You think God’s just going to do some light renovations—fix a leaky pipe, patch up the roof.
But instead, He starts knocking down walls, rebuilding the foundation, and turning your home into a palace fit for a King.
It’s uncomfortable, messy, and often painful.
But, oh, the beauty that comes from it!
Friend, Yahweh isn’t interested in making you a “nice person.”
He wants to make you a new person.

5. The Importance of Hope
In one of the most profound chapters, Lewis writes about hope—not the wishful thinking kind, but a hope anchored in eternity.
He reminds us that our longings for something “more” aren’t a curse. They’re clues.
As Lewis says, “If I find in myself desires which nothing in this world can satisfy, the only logical explanation is that I was made for another world.”
When life feels heavy, cling to this hope.
Revelation 21:4 assures us of the day when “God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying.”
A Challenge for You
As you reflect on these lessons, ask yourself: what’s holding you back from fully embracing this faith?
Is it pride, fear, or perhaps just distraction?
Friend, Lewis didn’t write Mere Christianity to entertain.
He wrote it to wake us up.
To show us that Christianity isn’t just a set of beliefs but the greatest adventure you’ll ever embark on.
So here’s my challenge to you: take the leap.
Whether you’re a lifelong Christian or just starting to explore faith, dig deeper.
Pray.
Surrender.
Trust.
And watch as Yahweh transforms your life in ways you never thought possible.
