That’ll Preach

How do we understand the relationship between the Persons of the Trinity—and why does it matter?

We sit down with Dr. Blair Smith, President of RTS Charlotte to talk about the centrality of the Trinity to Christian faith and practice, common misconceptions about “eternal generation”, modern misunderstandings about hierarchy and subordination in the Trinity, and how a Trinitarian theology transforms our prayer life. If you care about understanding God rightly—and living in deeper communion with Him—you don’t want to miss this episode.

In this episode, we’re joined by Andrew Koperski (Hillsdale College, Ad Fontes) to explore one of the most debated and often misunderstood practices in the history of Christianity: baptism. Drawing from his in-depth research, Andrew takes us through the earliest Christian sources—from Second Temple Judaism to Justin Martyr, and from household baptisms to the evolving liturgical traditions of the early church.

We discuss:

Did the earliest Christians baptize infants or only professing believers?

How did the theology of the church fathers evolve and adapt to the shifting environment of the Roman Empire?

What role does sociology play in the development of infant baptism?

Why modern categories of “credobaptist” and “paedobaptist” may not neatly map onto the early church.

What happens when church leadership stops being a one-man show? In this episode, we sit down with Dave Harvey, President of The Great Commission Collective, to discuss his book The Plurality Principle We dive into why shared leadership isn’t just a good idea, but a biblical necessity, how to navigate power dynamics among elders, and what happens when churches get plurality wrong.

Dave shares insights on leading well, avoiding burnout, and creating a team that thrives—not one that just survives. We also discuss the role of a “first among equals” and why accountability is essential for long-term health in church leadership.

In this episode, we explore the significance of Ash Wednesday and the season of Lent—40 days of repentance, mourning, and fasting in preparation for Easter. Drawing parallels to an athlete’s disciplined training, we discuss how fasting trains us to rely on God’s Word rather than our appetites. Jesus Himself calls us to fast, and through this practice, we create space for prayer, reflection, and repentance. We dive into the deeper purpose of fasting, how it sharpens our prayers, and how it helps us live in greater dependence on God.

Lent is more than giving up social media—it’s a season of discipline, abstinence, and reliance on God. In this episode, we explore the history of Lent, common misconceptions, and the purpose of fasting. True fasting disciplines both body and soul, teaching us to depend on God rather than our most basic needs. If we can’t give up a meal for Christ, how can we give up our lives? Join us as we reflect on Jesus’ 40 days in the wilderness and what it means to live by every word from the mouth of God.

What if every pastor had access to deep, biblical theological training—no matter where they lived?

In this episode, we sit down with John Miller, Vice President and Academic Dean at Covenant Baptist Theological Seminary, whose mission is nothing short of transformational. With a burning passion to equip indigenous pastors, John is spearheading efforts to plant seminaries around the world, ensuring that church leaders in Africa, Asia, and beyond have the theological foundation they need to shepherd their congregations faithfully.

John shares his personal journey—how God led him from the classroom to the frontlines of global theological training. He paints a picture of the urgent need for solid biblical education in regions where pastors often lead churches with little to no formal training. We’ll hear powerful stories from his work overseas, the challenges of building sustainable seminaries, and why equipping local leaders is the key to lasting gospel impact.

In the final episode of our series on Brother Lawrence’s Practicing the Presence of God, we explore how to bring his insights into our daily lives. Can we truly experience God as he did, or are his claims too lofty or unrealistic? We also discuss how serving others and fostering friendships can indirectly deepen our awareness of God’s presence, offering practical ways to grow spiritually.

It’s no secret that many Christians feel disoriented when it comes to understanding the relationship between faith and politics. Much of this confusion comes from the fact that we’ve adopted a modern conception of freedom. To the modern mind freedom refers to the ability to do whatever you want, but what if that assumption is wrong? What if Christianity provides a concept of freedom that’s not only true, but beneficial for the common good? Brad Littlejohn joins us to talk about a Christian conception of freedom, a proper understanding of religious liberty, and the role of technology in shaping our society for good or ill.

We continue our series on Brother Lawrence’s classic work Practicing the Presence of God by focusing, no pun intended, on the topic of attention. One of the great insights that Brother Lawrence brings to the table is the reality that attention to God is something we train through discipline and practice. It’s not something that happens over night which challenges us to consider the ways distraction prevents us from awareness of God. We also talk about how what we pay attention to either forms or deforms us based upon what we focus on as well as how a lack of attention may lie behind every sin.
