Seven Authors Who Helped Shape My Theology

Seven Authors Who Helped Shape My Theology
There are moments in a person’s faith journey where they realize they did not arrive at their understanding of God alone. Scripture is always the foundation, but along the road there are voices—pastors, theologians, revivalists, and writers—who help illuminate the path. Their words sharpen our thinking, challenge our assumptions, and sometimes ignite a deeper hunger for God.
As I reflect on the writers who have influenced my own theological thinking, I recognize that each of them shaped a different part of how I understand faith, Scripture, reverence for God, and the power of the gospel. Some of them helped me think more deeply. Others helped me feel the weight of holiness. Some awakened a longing for revival. Others helped organize the truths of Scripture in a way that made them clearer.
Below are several authors whose writings have had a meaningful impact on my theology and spiritual life

Her story is one of the great revival narratives in Christian history. Reading about her ministry awakened something in me about the possibility of revival and the reality that God still moves powerfully among ordinary people. Her life reminds me that faith is not merely intellectual—it is living, active, and capable of transforming entire communities.

Piper helped shape my understanding of the glory of God and the seriousness of pursuing joy in Him. His teaching that God is most glorified in us when we are most satisfied in Him deeply influenced how I think about worship, obedience, and the purpose of the Christian life.

Chandler’s preaching constantly brings the conversation back to the gospel. Through his teaching I have been reminded again and again that the center of Christianity is not self-improvement or religious performance, but the finished work of Christ.

Lewis has a remarkable ability to communicate profound theological ideas with clarity and imagination. His writings helped me see how faith and reason can coexist, and how storytelling and theology can sometimes illuminate truths that pure argument cannot.
Through his teaching on the fear of the Lord, Bevere helped reintroduce an important dimension of the Christian life: reverence. His work challenged me to see that God is not only loving and merciful, but also holy and worthy of deep respect and awe.

Often called the “Prince of Preachers,” Spurgeon combined theological depth with a burning love for Christ. His sermons reveal a deep understanding of Scripture and a pastoral heart that speaks directly to the struggles of ordinary believers.

Grudem’s work in systematic theology has helped bring structure and clarity to many areas of Christian doctrine. His writing helped me understand how different biblical teachings connect together into a coherent framework of belief.

As I look back on these influences, I am reminded that theology is rarely formed in isolation. It is shaped through Scripture, prayer, community, and the wisdom of those who have spent their lives studying and proclaiming the truths of the gospel.
Each of these voices contributed something unique to my journey. Some stirred my heart toward revival. Some sharpened my mind to think more clearly about doctrine. Others reminded me of the reverence and wonder that should accompany any attempt to understand God.
Ultimately, every author we read is simply pointing beyond themselves to something greater. Their writings may guide us, challenge us, and inspire us—but the final authority for faith and life always returns to the Word of God.
I am grateful for the voices that have helped shape my thinking, and I continue to approach theology as a lifelong journey of learning, humility, and deeper devotion to Christ.

A Week Ignited: Brotherhood, Openness, and the Quiet Work of God

By Dylan Verdun Sullivan
Wow  what a start to the week. I’ve been sitting with Saturday for a couple of days now, letting it settle, letting it breathe, letting it speak in its own way before rushing to put words around it. There are moments in life that are better written immediately, while the emotion is still raw and close to the surface. But there are other moments that need time—time to process, time to reflect, time to understand what was actually taking place beneath what we could see. Saturday felt like one of those moments. Kings Church connect group at Paradise Point . A simple setting on the surface. A lunchtime barbecue. Men gathered. Food cooking. Conversations unfolding. Nothing overly structured. Nothing forced. But what took place in that space carried far more weight than what it looked like from the outside. And I think that’s what has stayed with me the most. Letting the Moment Settle I was going to write on Saturday. I really was. I felt it stirring in me as I left. Tha...

An Unsent Beginning

By Dylan Verdun Sullivan
 Some words aren’t written to be understood. They’re written because they refuse to stay inside. This space exists for the things I never sent , the thoughts that didn’t belong in conversations, the prayers that didn’t resolve into answers, the moments that were too honest for performance. I’ve learned that not everything needs a destination. Some things just need a place to rest. What you’ll find here won’t be lessons or instructions. There will be no tidy endings, no motivational arcs, no promise that pain always makes sense in hindsight . There will be faith, but not the polished kind. There will be struggle, spoken quietly. There will be days when hope is loud and days when it barely whispers. This is not a journal written for an audience. It’s a record of what survives the day. What remains after the noise has burned off. What’s left when honesty is the only option. If these words resonate, that’s enough. If they don’t, that’s also enough. Some letters are never sent because t...

Christ in the Middle of the Fire

By Dylan Verdun Sullivan
This week has been a beautiful mixture of struggling with past wounds and patterns and deep revelations from Christ. Some weeks feel heavy in ways that are difficult to explain. Old memories surface, patterns you thought you had already buried rise again, and you begin to see parts of yourself that you wish were not still there. But at the very same time, there are also moments where Christ reveals something deeper, something clearer, something that steadies the soul in the middle of the struggle. That is what this week has felt like. A strange but beautiful tension between wrestling with the past and experiencing fresh understanding of who Jesus really is. Bible college yesterday became a powerful foundation for the entire week. As I sat among other students and opened the Scriptures together, I felt that quiet sense again that God is forming something in my life. The topic that anchored our study was the apostle Paul’s letter to the Ephesians . The book of Ephesians is one of those...

Learning to Think Deeply About God in the Middle of Life

By Dylan Verdun Sullivan
 There are seasons in life when the mind begins to slow down and look more carefully at the deeper things. Not because everything is suddenly calm. Not because all of life’s questions have been answered. But because something inside you begins to hunger for understanding in a deeper way than before. That is the season I find myself in right now. For much of my life, faith was something deeply personal. It was something I clung to in moments of pain, moments of fear, moments when life felt as though it could collapse beneath the weight of circumstances. Faith was not theoretical for me. It was survival. It was the quiet anchor that kept me steady when everything else felt unstable. But over time, something else began to grow alongside that faith. A desire to understand. Not simply to believe that God is real, but to think deeply about who He is. To explore the theology behind the truths that had already become real in my life through experience. That desire has led me into a season ...

The Echoes of Fire: From Pentecost to the Present

By Dylan Verdun Sullivan
It’s been a few days since I’ve sat down to write. Not because there hasn’t been anything happening—but because something deeper has been unfolding beneath the surface. I’ve found myself going down what I can only describe as a spiritual rabbit hole, and it has been difficult to step away from it. And it all began—or at least deepened—as I continued restoring Holy Ghost Sermons by Maria Woodworth-Etter   What started as a restoration project has slowly become something else. It’s no longer just about correcting text, fixing errors, or preserving structure. It’s become an encounter. Because as I’ve been sitting with her words, I’ve found myself asking a question that hasn’t left me: Where did this kind of fire come from? And that question didn’t just take me back a few years. It took me all the way back to the beginning. Pentecost — Where It All Began Before there was revival history, before movements had names, before there were books or testimonies being recorded— There was a roo...
