The Mind Matters: How Your Thoughts Affect Your Faith and Relationship with God

Lately, I’ve been reading and listening to The Power of Positive Thinking by Norman Vincent Peale, and it’s brought something to the surface that I can no longer ignore: the power of our thoughts, and how deeply they influence our faith, our prayers, and ultimately, the way we experience God.

This book reminded me of moments in my own walk with God—times when I believed without reservation, and God showed up in ways that left me speechless. And then, there were other moments. Times when my doubt spoke louder than my faith. Times when I couldn’t even bring myself to believe fully, and unsurprisingly, nothing happened.

I’ve come to realise that our thoughts are not neutral. They either water our faith or slowly drain it. And in the world we live in—where bad news travels faster than light, where pressure mounts from every direction—choosing a positive, faith-filled mindset isn’t just helpful, it’s essential.

Why Positivity and Faith Are Spiritually Connected

Some people hear the word “positivity” and assume it’s just feel-good fluff or motivational talk wrapped in Christian lingo. But in truth, the Bible is saturated with the call to renew our minds (Romans 12:2), cast down imaginations (2 Corinthians 10:5), and think on things that are pure, lovely, and praiseworthy (Philippians 4:8).

Positivity isn’t just about being upbeat—it’s about coming into agreement with what God says about you, about your situation, and about your future.

Faith doesn’t thrive in a mind overrun by negativity. Faith is choked when we constantly dwell on the worst outcomes or allow fear to run wild. But when we choose to focus on God’s promises, even when the reality around us is bleak, we step into a different atmosphere—one where God can move powerfully.

How I Stay Positive (Even When Everything Screams Otherwise)

Let me be real—it’s not always easy. There have been days, and even seasons, when everything around me screamed negativity, sadness, and defeat. In those moments, my natural tendency is not to be hopeful—it’s to retreat. To overthink. To assume the worst.

But here’s what I’ve learned: I cannot afford to let my mind wander aimlessly. I must guard it intentionally. So here’s how I fight to keep my mind and spirit aligned with faith, even when I don’t feel it:

1. I Fill Every Gap with Life-Giving Content

When I’m struggling mentally or emotionally, I make sure every free moment—while driving, cooking, walking—is filled with messages, audiobooks, or worship that lift my spirit. Silence is not always my friend in these moments. I can’t afford to “slip” mentally, because that’s when doubt starts whispering.

2. I Talk to People Who Uplift Me

We all know the kind of people we can go to when we’re feeling low—the ones who won’t just agree with our sadness but will gently challenge us to remember who we are and Whose we are. I lean into those conversations when my faith is weak. I let their words remind me that I’m not alone and that this, too, shall pass.

3. I Read the Word and Remember God’s Track Record

Sometimes I go back to stories in Scripture—not just for theology, but for testimony. If God came through for Hannah, Joseph, David, and Paul, why not me? I read about the Red Sea parting or prison doors flinging open, and I remind myself: this is the same God I serve today. I also reflect on testimonies from people I know. If He did it for A and B, in the same situation I’m in, He will do it for me.

4. I Depend on the Holy Spirit

When it feels like even thinking positive is too hard, I ask the Holy Spirit to help me. The beautiful thing about grace is that God isn’t waiting for me to pull myself together before He steps in. Sometimes all I can do is whisper, “Help.” And that’s enough.

The Benefits of a Faith-Filled, Positive Mindset

When we consistently choose positivity rooted in God’s promises, the impact is undeniable:

• We regain perspective — seeing trials as temporary and God as sovereign.

• Peace takes root — not because everything is perfect, but because we trust the One who holds it all together.

• Fear loses its grip — when we start speaking life and truth, fear has less space to operate.

• We’re spiritually stronger — our faith grows sharper, and we’re more prepared for the battles life throws our way.

• We become beacons to others — people around us begin to ask how we stay grounded, and it opens the door for witness.

But let’s not pretend it’s always smooth. There are days when it feels like your mind is in a fog and faith feels far away. And that’s okay. It doesn’t mean you’ve failed. It just means you need to re-anchor.

Recommended Reads and Resources

You don’t need a library of books or a hundred YouTube messages to shift your thinking. Often, one powerful message, one Scripture, or one book is enough to redirect your mind and stir your faith again.

Here are two I recommend:

• The Power of Positive Thinking – Norman Vincent Peale

  A timeless book that helps you break through mental defeat and renew your mind through biblical truth and practical steps.

  
  

• Winning the War in Your Mind – Craig Groeschel

  A modern, relatable guide to taking control of toxic thoughts and replacing them with God’s truth.

Don’t underestimate the power of a single verse. One truth can become your lifeline in stormy waters.

Final Encouragement: God Is for You

If you’re in a place right now where fear feels louder than faith, take heart—God isn’t disappointed in you. He knows the fight you’re in. And He’s right there with you.

Faith isn’t about pretending nothing’s wrong. It’s about believing that even in the chaos, God is still good, and He is still in control.

Your mind matters. What you think affects how you believe. So guard it. Nourish it. Fill it with life, truth, and hope.

Because when your thoughts align with your faith, you step into the space where miracles happen.

You are stronger when you’re sharper in faith. So protect your thoughts. Choose life. And remember: God’s plans for you are still good.
