Monitoring the Soul: A Review of Multiplier by Dave Ferguson

At the start of Multiplier, released in 2026 by Zondervan Reflective and Exponential Resources, author Dave Ferguson writes, “You reproduce who you are and what you do.” Through Multiplier, Ferguson helps us see that “we reproduce not just what we teach, not just what we hope, but who we actually are and what we actually do.” The reality is that we all reproduce ourselves and influence others through what we say, do, and embody, whether intentionally or not. If we are not careful, that unintentional influence could distort and become disconnected from what we intend to communicate. For that reason, Multiplier calls us to “commit to becoming people who are worth multiplying.” This is a journey of discovering what we are currently reproducing, hearing from God regarding what he has entrusted us to reproduce, and setting guardrails to keep us faithful in multiplying what he has placed within us.

We live in a world that craves stages and visibility; the purposes and leadership opportunities in our lives are often seduced by the pursuit of larger crowds, bigger buildings, and broader brands. However, when I began writing about the “Quiet Way,” and what it means to lead a quiet life, I realized that God desires something deeper from the Church. To lead a quiet life is to live with a stillness and a radical dependency on God in every dimension of our existence. We don’t need more leaders chasing “influence”; we need leaders who work with their hands and faithfully steward the specific places they have been planted.

In Multiplier, Dave Ferguson calls us to exactly this kind of localized faithfulness. He defines our primary task as being faithful to Christ in whatever capacity we hold—in the places we live, work, worship, and play. When we intentionally disciple others in those ordinary spaces, to be faithful in ordinary ways, we move away from the “consumeristic” model and toward a movement of people who simply live and love like Jesus. Small acts of faithfulness lead to great kingdom movements. We must trust that as we work with our hands and lead quiet lives, God will multiply the kingdom of God in small, authentic, and everlasting ways. We don’t need more stages; we need sages for the intersections of everyday life.

I believe this book will be part of Dave Ferguson’s legacy to Christian and church leaders. It provides profound insight into leading well across every dimension—from physical health to spiritual depth—and calls us to be intentional with exactly what we are multiplying in the world around us.

We need healthier leaders.

An Inside Look at Multipliers by Dave Ferguson

This deeply formative book is thoughtfully structured into four distinct parts, beginning with an introduction that sets the stage for the journey ahead. In Section 1, Ferguson unpacks the four “gauges of a multiplier,” providing the internal diagnostic tools necessary for health, while Section 2 explores the four external practices of a multiplier that lead to movement. The book then culminates in Section 3 with a challenging call to embrace and sustain the life of a multiplier in every sphere of influence.

This deeply formative book is thoughtfully structured into four distinct parts:

• The Introduction: Sets the stage for the journey ahead.
• Section 1: Unpacks the four “gauges of a multiplier.”
• Section 2: Explores the four practices of a multiplier.
• Section 3: Offers a challenging call to live the life of a multiplier.

I found Multiplier to be a revolutionary and reflective read. It contains some of the most practical guides I have ever encountered, delivered with remarkable transparency. I hope this book goes far with its prophetic challenge to be intentional with exactly what we are multiplying in the world around us. I hope it is a gateway to more conversations and resources on this very topic. This is one of the challenges the evangelical and Christian church needs the most in this era.

I wish every leader would read this book. Please don’t read it as a formulaic guide; instead, see it as a resource for practices that have anchored and transformed Dave Ferguson. These are the same tools that have already begun to transform my life and leadership over the past few years, providing a steady foundation in a restless world.

Leaders formed in quiet ways will overflow in ordinary spaces in transformative ways.

The High Cost of Unhealth

The last half-decade has been marked by a staggering number of high-profile leaders leaving their ministries amidst turmoil and trouble. Ferguson’s work provides a sobering look at how underdeveloped areas of our lives become the very places exploited by sin. When these internal gauges are ignored, they eventually lead us to inflict damage and destruction on the people and missions we were called to steward. These failures are a stark reminder that the greater the influence, the more catastrophic the fall. Ferguson shares stories about how the undeveloped and shadow parts of our lives have brought down leaders both in his area and those he has known. Too often, we have been impressed by capability more than by character and have translated blessings as God’s confirmation.

To this end, there is a weight of warning found in Ferguson’s warning that we must not confuse God’s blessings with God’s approval. Far too many leaders, distracted by their own power and perceived success, miss the reality that external growth is not a divine confirmation of internal health. As Ferguson notes, “The higher you go, the greater the impact of your missteps,” and “with more external influence comes greater personal responsibility.” Even in God’s kindness, God’s blessings are intended to drive us “to repentance, not to confirm our complacency,” Ferguson reminds us. The way Ferguson unpacks these realities is both timely and necessary for a generation of leaders tempted to prioritize curating the stage over curing the soul.

Almost all leaders start with good intentions, but Ferguson warns that “we start out with a commitment to our own well-being and a bold vision, but somewhere along the way we tend to drift.” Drift occurs slowly, one day at a time, until we find ourselves in unintended territory. Ferguson attributes this to the “drift trio”: the world, the flesh, and the devil. I would add one thing to Ferguson’s list: immaturity. Often, our lure isn’t defined by outright selfishness or spiritual warfare, but by the inability to tell the difference between a “good thing” and a “God thing.” Sometimes we are simply too immature to make wise discernments, and drifts happen despite our best intentions.

This book, though, gives us the stages and small steps that slowly get us back on track, one day at a time, until we find ourselves back in healthy territory.

The damage left by unhealthy leaders has been irreparable.

More than ever, leaders should be walking away from microphones and stages and simply being faithful to the things of Jesus in small, ordinary ways.

Multiplier: Monitoring the Soul

The strongest and most impactful aspect of Multiplier is how Dave Ferguson calls us to intentionally monitor the health of our souls. He identifies four specific gauges—spiritual, relational, physical, and mental—which Ferguson calls the “RPMS.” These are not merely theoretical concepts; they are tools he has utilized in his own life for over a decade, believing they can “monitor how you are doing and develop who you are.” This framework serves as a practical, confessional guide for journaling, spiritual direction, and the communities of accountability we are called to inhabit.

Influence and multiplication are God’s work.

The question for every leader is no longer just how much we can produce, but whether we have the courage to look at our own gauges before the “slow leak of wonder” becomes a catastrophic engine failure.

Influence and multiplication are byproducts of our spiritual health.

Dave often blogs about this on his Substack, and I encourage you to check it out.

Tired Leaders Distort What We Multiply

Ferguson highlights a sobering reality: most modern leaders are “exhausted, stretched thin, and unsure how to keep going, let alone multiply.” As a writer, doctoral student, and pastor serving in two distinct contexts, I know firsthand that these seasons of depletion are never far off. While such seasons are perhaps inevitable, the danger for a leader lies in our tendency to ignore them when we are exhausted and stretched thin. The RPMS gauges do more than just signal when we are running on fumes; they pinpoint exactly where God is inviting us into a deeper, modeled dependency on God’s Spirit. Ferguson’s central premise remains unshakeable: “You can’t multiply something that’s not first alive in you.” How we pay attention to our relational, physical, mental, and spiritual “gauges” will define what we are multiplying in others, in the world around us, and in our faith communities.

When the light comes on in our car’s dashboard, we take it into the shop.

We don’t ignore it; we know that a flickering light is a warning of a future breakdown.

If a light is on in our relational, physical, mental, or spiritual health gauges, we need to pull over and pay attention before we spin out of control.

We cannot simply “push through.”

Dave gives us warning lights to pay attention to as a divine invitation to stop running on fumes and return to a radical dependency on God.

A Diagnostic for the Soul from Dave Ferguson

The core of Ferguson’s internal diagnostic is the “RPMS” framework, which challenges leaders to monitor four specific gauges: Relational, Physical, Mental, and Spiritual health. These are not merely abstract concepts, but tools Ferguson has road-tested in his own life for over a decade to “monitor how you are doing and develop who you are.” In practice, the RPMS serves as a practical, confessional guide that invites leaders into deeper layers of accountability. Whether used as a template for daily journaling, a focal point for meetings with spiritual directors, or a shared language within a leadership team, these gauges pinpoint exactly where we are running on fumes. They help us identify the specific areas where God is inviting us into a modeled dependency, ensuring that our leadership flows from a well that is actually being replenished.

I don’t have time to tell you the many layers and practices Dave gives us in relation to RPMS health, but they are good and important. At least hear this: these four areas, given honest reflection, will tell you what you are leading on and multiplying outwardly.

A Necessary Resource for the Modern Leader

I cannot recommend Multiplier highly enough; it is a resource I wish every leader would prioritize. A few years ago, I loved Dave’s Hero Maker. It was a book I had led many groups through. Now Ferguson gives us perhaps his best work yet. Ferguson offers a collection of unmissable stories—ranging from the sobering failures of leaders in the Chicagoland area to the inspiring successes of healthy leaders in global movements. Interwoven with these narratives are profound scriptural insights that reframe leadership development not as a corporate pipeline, but as a God-honoring mission to see the life of Christ reproduced in others. This book is challenging, leading us out of the exhaustion of ministry into healthy lifestyles and a well-stewed vocation. This book, Multipliers, provides the practical practices and spiritual guardrails necessary to stay healthy, stay faithful, and lead from a place of “holy fire” that is truly worth multiplying.

I believe that through Multipliers, Dave Ferguson will inspire a generation of new leaders with new, deeper practices and greater integrity.
