    Sermon Brainwave 1069: Ash Wednesday - February 18, 2026

    Sermon Brainwave Episode 1069: Ash Wednesday — Practicing Righteousness in Times of Crisis Join hosts Karoline Lewis, Matt Skinner, and new co-host Cody Sanders for this Ash Wednesday podcast as they explore the lectionary readings for February 18, 2026. This episode introduces Cody Sanders, Associate Professor of Congregational and Community Care Leadership at Luther Seminary, who brings a Baptist perspective and pastoral care voice to the Sermon Brainwave team. The hosts examine Joel 2:1-2, 12-17, Psalm 51:1-17, 2 Corinthians 5:20b-6:10, and Matthew 6:1-6, 16-21, exploring critical questions about righteousness, forgiveness, and reconciliation. Karoline highlights the significant translation shift in Matthew 6:1 from "piety" to "righteousness" in the NRSVUE, connecting it to the Sermon on the Mount's opening theme of hungering and thirsting for righteousness. Matt and Cody discuss the distinction between forgiveness and reconciliation, emphasizing the importance of careful, compassionate preaching on these topics, particularly in contexts of abuse and violence. Cody draws on historic faith communities—including enslaved people in hush arbors and LGBTQ believers exiled from their churches—to illustrate what it means to be "treated as imposters yet are true, having nothing yet possessing everything." This episode provides practical sermon preparation insights while addressing the affective dimension of faith in challenging times, making it essential listening for preachers navigating Ash Wednesday and the Lenten season.

    Sermon Brainwave 1068: Transfiguration of Our Lord - February 15, 2026

    In this Sermon Brainwave episode, hosts Rolf Jacobson, Karoline Lewis, and Matt Skinner explore the Transfiguration of Jesus from Matthew 17:1-9 for Transfiguration Sunday (February 15, 2026). The team examines how this pivotal moment bridges the season of Epiphany and the journey into Lent, highlighting God's voice declaring "This is my son, the beloved" and the crucial addition: "listen to him." The conversation unpacks why the disciples are terrified not by seeing Jesus transformed, but by hearing God's voice—and how Jesus' compassionate touch and words "get up and do not be afraid" offer reassurance for facing the unknown. The hosts discuss the significance of Moses and Elijah as eschatological figures, the narrative context following Jesus' predictions of suffering, and how the glory of the mountaintop contrasts with the immediate return to ministry in the epileptic boy's healing. Drawing on Mark Throntveit's powerful sermon framework, the team contrasts two mountains: the Transfiguration's radiant glory with Moses and Elijah versus Calvary's darkness with two thieves. Both mountains declare "This is my son," yet reveal the Jesus we want versus the Jesus we get. In a special moment, Rolf Jacobson announces his departure from the podcast to focus on his academic dean responsibilities and launch a new podcast series on Rudolf Bultmann, with colleague Cody Sanders stepping in to continue Sermon Brainwave's work.

    Sermon Brainwave 1067: Fifth Sunday after Epiphany - February 8, 2026

    Join hosts Rolf Jacobson, Matt Skinner, and Karoline Lewis as they explore the Fifth Sunday after Epiphany lectionary readings for February 8, 2026. This episode dives into Matthew 5:13-20, where Jesus declares "You are the salt of the earth" and "You are the light of the world" - not as invitations, but as statements of fact about Christian identity. The hosts unpack what these metaphors meant in the ancient world. Salt served as both a flavor enhancer and a crucial preservative in a society without refrigeration, making it essential for sustaining life. Light represents the impossibility of keeping faith private in a pluralistic world. These aren't suggestions for what Christians might become, but declarations of who they already are. The conversation explores how believers manifest the kingdom of heaven through their identity as salt and light. The discussion connects this gospel passage with Isaiah 58:1-9a, which challenges fasting practices and calls for genuine justice, Psalm 112:1-9 about those who fear the Lord, and 1 Corinthians 2:1-12, where Paul discusses God's hidden wisdom revealed through the Spirit. Rolf shares insights from his new book "God Meets Us in Our Suffering," connecting Paul's theology of the cross to how God meets us not primarily in our glory and success, but in the places where we think it's impossible for God to be. The conversation emphasizes that having "the mind of Christ" means participating in God's life through the Spirit, not just receiving benefits from Christ's death. Discover how these ancient texts speak to modern questions about public faith, Christian identity, and what it means to be caught up in the life of God.

    Sermon Brainwave 1066: Fourth Sunday after Epiphany - February 1, 2026

    Join Matt Skinner, Karoline Lewis, and Rolf Jacobson for an exploration of the Fourth Sunday after Epiphany lectionary texts. This episode unpacks the Beatitudes as Jesus' mission statement and inaugural address, revealing where God's kingdom breaks into the world. The hosts discuss how Matthew's Beatitudes function as Jesus' announcement of the people he will be found with—those the world overlooks or considers unblessed. Matt Skinner explores how these verses bracket Matthew's entire gospel ministry with deep compassion and mercy. Karoline Lewis highlights the transition in the Beatitudes from blessing to action, showing how disciples participate in God's alternative community. Rolf Jacobson connects the Beatitudes to the crowds of suffering people who followed Jesus at the end of Matthew chapter 4. The conversation tackles Micah 6:1-8, examining its powerful indictment and the call to justice, kindness, and humble walking with God. The hosts place this famous verse back into its original context, challenging surface-level readings. The discussion of 1 Corinthians 1:18-31 focuses on Paul's theology of the cross. Rolf explains how Paul argues that the world cannot know God through human wisdom alone—the cross is God's fundamental revelation. Matt introduces Michael Gorman's concept of "cruciformity," exploring what it means to be a cross-shaped community. The hosts connect Paul's message about God choosing the foolish, weak, and lowly to the Beatitudes' vision of blessing. This episode offers preachers and biblical educators practical insights for sermon preparation, showing how these texts speak to contemporary issues of power, blessing, and God's upside-down kingdom.
