- 54 minutes 54 secondsThe Strange Relief of a Grace-Shaped Life (w/ David Zahl)
Many Christians wrestle with anxiety, discouragement, and even thoughts of despair. Our performance-driven culture distorts our view of God and grace, leaving us feeling exhausted and hollow. In this episode, Jon interviews David Zahl about his new book: “The Big Relief.” We discuss how grace reorients our lives, bringing joy, purpose, and rest for weary souls. If you’re craving real relief, this conversation is for you.

10 December 2025, 11:05 am - 44 minutes 16 secondsThe Prosperity Gospel Test
You probably don’t believe in the prosperity gospel, at least not the version that promises wealth and health in exchange for faith or donations. But what if traces of it still influence your Christian life? In this episode, Jon explores how transactional thinking subtly creeps into the hearts of even Reformed believers. We often assume God's nearness or blessing is based on our performance, which can rob us of joy and rest in Christ. This episode aims to expose hidden prosperity thinking and point you back to the comfort of the true gospel.
3 December 2025, 11:05 am - 46 minutes 10 secondsWhy Do I Still Struggle with Sin? (w/ Luke Kjolhaug)
Have you ever wondered, “Why do I still struggle with this?” Many Christians expect that with maturity, temptation will decrease and sin will lose its appeal. But Scripture offers a more realistic view. In this episode, we talk about the saint-sinner reality. How believers remain both righteous in Christ and yet still battle the flesh. Jon is joined by special guest pastor and author, Luke Kjolhaug, to explore what the Bible actually says about spiritual growth, expectation, and daily struggle.

26 November 2025, 11:05 am - 42 minutes 41 secondsThe Prison of Self-Preservation
Do you ever feel alone, like something is just wrong with you? Many people silently wrestle with loneliness while living in a culture that celebrates self-prioritization and self-love. But instead of healing us, this only leads to deeper isolation. In this episode, Jon reviews a thought-provoking video and discusses a humble truth about why loneliness persists and how the gospel offers real liberation. Stay tuned for hope and clarity.
19 November 2025, 11:05 am - 39 minutes 18 secondsWhen In Despair... (w/ Chad Bird @ 1517)
Do you ever feel stuck in despair, wondering if God is still near? In this conversation, Jon Moffitt, Justin Perdue, and Chad Bird discuss how Christ meets us in our darkest moments with real comfort and sustaining grace. Recorded live at 1517’s Here We Still Stand 2025 Conference in San Diego, we explore how the Psalms, the church, and the gospel itself anchor us when life feels overwhelming. This conversation reminds weary sinners that our hope is not in ourselves but in Christ alone.
29 October 2025, 10:05 am - 24 minutes 41 secondsJesus and the Accuser (w/ Chad Bird & Ken Jones)
Satan’s primary weapon against believers is accusation, especially when we fail. At our recent Law-Gospel conference, Justin Perdue preached on Jesus and the Accuser, showing how Satan targets our assurance and tempts us to trust our own righteousness or despair entirely. What follows is a panel discussion with Chad Bird, Ken Jones, Justin, and Jon Moffitt, diving deeper into how Christ defends us when Satan attacks. If you want to hear the full lecture, check out the link below. This panel discussion stands on its own and offers real hope for those battling doubt.

22 October 2025, 10:05 am - 26 minutes 32 secondsGospel VS Law Based Living (w/ Chad Bird & Ken Jones)
What truly motivates the Christian life: the gospel or the law? Too often, we confuse gospel-driven living with law-based performance. This panel discussion, recorded live at our 2025 Theocast Conference, explores how the distinction between law and gospel shapes our motivations, obedience, and joy in Christ. Featuring a post-lecture conversation with Chad Bird, Ken Jones, Justin Perdue, and Jon Moffitt, this episode unpacks what it means to live by grace. If you're tired of legalism and looking for gospel clarity, this one's for you.

15 October 2025, 10:05 am - 42 minutes 3 secondsIs the Gospel Really That Simple?
I regularly sit across the table from people and ask them to tell me the gospel. I can see how nervous and anxious that question makes them. Maybe you have had that experience: someone asks you, "What is the gospel?" and suddenly you do not know how to respond. You worry you might not say the right thing. Often this happens because we have made the gospel far too complicated in the way we talk about it. That robs us of the peace, hope, and assurance the Lord intends for us to have. The gospel is unfathomably deep, yet it is also beautiful in its simplicity. Jon and Justin have a conversation about that today. We hope it encourages you.
8 October 2025, 10:05 am - 46 minutes 44 secondsWhen Christians Hurt Each Other
Justin and Jon love this phrase: All of Christ for all of life. That is what this podcast is about today. The doctrine of Christ is important, and we need to get it right—but it is also for our daily lives. This is where it becomes a balm and a joy. It allows us not only to have rest but also to give rest. So we want to talk about what all of Christ looks like in areas such as relational conflict. How do we apply the wonders of Jesus for us, and how do we use something like the third use of the law to proclaim the light of the Kingdom while resisting the darkness? We live in a dark world, so considering all of Christ in conflict is a really important conversation. It was helpful for us, and we hope it will be encouraging for you as well.
1 October 2025, 10:05 am - 35 minutes 51 secondsTempted? Welcome to Christianity
Something I wish Christianity would address more often is the normal battle with sin. Or, to put it another way: temptation. Temptation is a normal experience. That word "normal" is the key. We tend to think that as we grow in Christ, temptation decreases. But that is not what Paul says about our experience. It’s important to understand that you will not only struggle with sin, meaning you’re fighting it, but the temptation to sin may actually increase as you mature in the faith. Paul gives us some very important ways to think about temptation and how to endure it. This is a really important conversation. If you're struggling and feel the weight of temptation beating you down, this episode is for you.
24 September 2025, 10:05 am - 45 minutes 8 secondsMake Repentance Great Again
When I say the word repent, how do you feel? When I say confess your sins, what does that evoke in you? If repentance feels scary, threatening, or uncomfortable, or if confession feels the same, this podcast is for you. Jon and Justin are going to have a sweet conversation about how good God is to us, how forgiving and merciful He is, and how, since we have been united to Jesus by faith and brought into the family of God, it is actually a joy to live a life of continual repentance and honest confession of sin. We want to walk in the light together. There is real freedom and lasting joy in doing so. So let's make repentance great again.
