Sermon Brainwave 1022: Fourth Sunday of Easter - May 11, 2025
Welcome to another thought-provoking episode of Sermon Brainwave! This week, our hosts Karoline Lewis, Matt Skinner, and Rolf Jacobson dive deep into the lectionary texts for the Fourth Sunday of Easter (May 11, 2025)—including John 10:22-30, Acts 9:36-43, Psalm 23, and Revelation 7:9-17—with a special focus on Good Shepherd Sunday. We’ve all heard the image of Jesus as the Good Shepherd, but what if your understanding of that metaphor is incomplete—or even "lame," as the hosts boldly say? What if the image of shepherd is not just pastoral comfort, but a royal claim, a radical act of intimacy, and a call to relationship? 🔍 In this episode: - Discover why John 10:22-30 isn’t just a sweet sheep story but a bold revelation of Jesus’ divine identity. - Learn how Psalm 23 is about more than comfort—it’s about pursuit, provision, and power. - Explore the deeply human and touching story of Tabitha/Dorcas in Acts 9, a leader, disciple, and clothing maker whose resurrection reveals the personal and communal dimensions of new life. - Unpack the apocalyptic hope of Revelation 7, where the Shepherd becomes the Lamb, and where tears are wiped away for good. ✨ Whether you’re preparing to preach or simply longing to deepen your spiritual insight, this episode will equip you with fresh angles, biblical depth, and a few laughs along the way.
