What are catechisms and why do we use them?

To those unfamiliar with the term, “catechism” can seem like a strange word. Simply put, catechisms are question-and-answer tools that communicate Christian theology in simple ways. In this episode, we respond to a listener question about the origins of catechisms and creeds. We discuss why the Reformation led to a golden age of catechisms, what makes catechisms important, and how they connect us to historic Christianity and spur us to deeper worship.

In the wake of Charlie Kirk's assassination, how do we process our emotions, responses, and reactions?

On September 10, 2025, conservative political activist and outspoken Christian Charlie Kirk was murdered during a campus event at Utah Valley University. Some people are feeling shock, anger, fear, grief, and lament; others are celebrating or mocking. How do we make sense of what we’re feeling? How do we respond to what others are saying? And what does this moment portend for American politics and the future of civic debate? In this episode, Bob engages these questions and offers some commentary and perspective.

If you’ve listened to the radio lately, perhaps you’ve noticed that pop music is sounding a lot like worship music. Some of the year's most popular songs use biblical imagery, emotive builds, and vocal choirs—not unlike what you might hear in church. On this week’s episode, we discuss a recent article that traces this trend. We explore why music producers are mimicking worship music and what it suggests about our cultural moment.

Over the past half-century, evangelical Christians have rediscovered spiritual formation. Richard Foster, Dallas Willard, John Ortberg, and more recently John Mark Comer have helped re-emphasize spiritual practices and the interior life. But why does so much popular writing and teaching on spiritual formation lean on Catholic sources – mystics and monks and Merton? Is there a distinctly Protestant stream of spiritual formation that we can rediscover? If so, what might it teach us? In this episode, we interact with a new book from Matthew Bingham, A Heart Aflame for God. Bingham asserts that there IS a deep Protestant tradition of spiritual formation, and one of its distinctives is the centrality of Scripture. In this episode, we discuss why we tend to minimize Scripture in spiritual formation, why the Puritans saw Scripture as central to spiritual formation, and how we can practically foreground the Scriptures in our spiritual practices.

In credobaptist traditions, we baptize new Christians upon their profession of faith in Christ. But what happens when, a few years later, a new experience of God's grace makes me question my prior baptism? How can we separate our subjective experiences of God’s promises from the objective nature of those promises? In this episode, we respond to a listener question and discuss how the Reformation tradition understood baptism, what the animating force of baptism is, and the connections between baptism and discipleship.

If it hasn't happened to you yet... wait for it. Sometime in your mid-30's, life starts to feel mundane. You find yourself asking: How did I get here? Do I like what I do? Do I still want this job? Despite all the cliches, "mid-life crisis" is real. The world urges you to try something new - a new job, a new hobby, maybe even a new spouse. But what if God has a different invitation—one that invites you to interrogate your restlessness? In this episode, we answer a listener question about how to persist at work. We discuss stewardship, settling, friendship, and the wisdom of knowing your portion (Ecclesiastes 9:9).
