How Writing a Book Changed My Faith Walk

I thought I was writing a book. Turns out, God was writing me.

When I first set out to put my thoughts on paper, I expected a challenge—structuring ideas, finding the right words, maybe even some late nights wrestling with writer’s block. What I didn’t expect was how much the process would refine my faith. Writing a book wasn’t just about sharing truth; it was about being shaped by it.

Vulnerability: The Cost of Authenticity

If you want to write something that actually impacts people, you have to be real. That means exposing the raw, messy parts of your story—the ones you'd rather keep hidden.

I had to ask myself: Do I actually trust God enough to let others see my scars? It’s one thing to say, “God redeems brokenness,” but it’s another to lay that brokenness bare on a page. Yet, that’s exactly what Jesus did. After His resurrection, He didn’t hide His wounds—He invited Thomas to touch them (John 20:27). That moment wasn’t just proof of His resurrection; it was an invitation into deeper faith.

Writing forced me to do the same. I had to stop filtering my testimony to make it more comfortable. I had to be honest about the pain, the doubts, and the moments when I questioned everything. But in doing so, I saw God’s hand in my story more clearly than ever.

Faith: Trusting God with the Outcome

Faith isn’t just about believing in God—it’s about believing God. There’s a difference.

Every time I wrote a chapter, doubt would creep in. Is this even good? Will anyone read this? Am I wasting my time? The enemy loves to attack when we step into God’s calling. But God doesn’t call us to success; He calls us to obedience.

I kept coming back to Proverbs 3:5-6:

"Trust in the Lord with all your heart,
And do not lean on your own understanding.
In all your ways acknowledge Him,
And He will make your paths straight."

Writing a book tested my ability to trust that promise. I had to surrender my need for control—the fear of failure, the pressure to make it perfect, the anxiety over how it would be received. My job was to write in obedience. The results? That was God’s job.

Breaking Comfort Zones: Growth Through Resistance

Growth doesn’t happen in comfort.

Writing a book stretched me in ways I didn’t expect. It forced me to dig deeper into Scripture, to articulate my faith clearly, and to step into new roles—teacher, storyteller, even marketer. I had to put myself out there in ways that felt unnatural.

But God never calls us to stay where it’s safe. He calls us into deep waters (Matthew 14:29). Like Peter stepping out of the boat, I had to trust that even if I felt unqualified, God was the one holding me up.

Refinement: The Fire That Purifies

Writing exposed a lot of my weaknesses—perfectionism, fear of rejection, impatience. I had to face those things head-on. But that’s how God refines us.

1 Peter 1:7 says:

"So that the proof of your faith, being more precious than gold which perishes though tested by fire, may be found to result in praise, glory, and honor at the revelation of Jesus Christ."

Writing was my fire. It burned away pride, insecurity, and self-reliance. It forced me to lean into God more fully.

The Unexpected Blessing

Here’s what I didn’t see coming: Writing a book wasn’t just about reaching others. It was about God reaching me.

Every chapter deepened my dependence on Him. Every struggle taught me something about His character. Every moment of doubt reminded me that my story—like my faith—was never really in my hands.

If God is calling you to write, speak, or share your testimony in any way, don’t let fear hold you back. Say yes. Step out of the boat. Let Him use your words to not only impact others but to transform you in the process.

Because sometimes, the thing God calls you to create… is the very thing He uses to change you.
