Sermon Brainwave 1038: Eleventh Sunday after Pentecost - August 24, 2025
Join Matt Skinner, Karoline Lewis, and Rolf Jacobson on Sermon Brainwave as they explore the readings for the 11th Sunday after Pentecost (August 24, 2025). This episode dives deep into Luke 13:10-17, the powerful story of Jesus healing a woman with a crooked back on the Sabbath - a healing that's really about liberation and freedom. The hosts unpack the unique aspects of this healing story, including why the woman is called a "daughter of Abraham" (the only time this phrase appears in Luke), what it means that she's "set free" rather than simply "healed," and how this story challenges our assumptions about bodies, health, and spiritual freedom. They also explore the Sabbath debate and how Jesus operates firmly within Jewish tradition while expanding our understanding of what the Sabbath is truly for. Additional readings discussed include Isaiah 58:9b-14 (or Jeremiah 1:4-10 for semi-continuous readings), Psalm 103:1-8, and Hebrews 12:18-29. The conversation touches on themes of liberation theology, biblical interpretation, prophetic calling, and the pastoral care embedded in challenging theological concepts.

Join Karoline Lewis, Matt Skinner, and Rolf Jacobson as they dive deep into the lectionary readings for the 10th Sunday after Pentecost (August 17, 2025). In this episode, they explore the challenging theme of division that Jesus brings, not as his goal, but as an inevitable result of following his way.

Sermon Brainwave 1035: Eighth Sunday after Pentecost - August 3, 2025
The Rich Fool, Ecclesiastes, and Finding True Wealth. Join Matt Skinner, Karoline Lewis, and Rolf Jacobson as they dive deep into the challenging texts for the Eighth Sunday after Pentecost (August 3rd, 2025).

The conversation also explores the challenging pairing of this text with Ecclesiastes, examining the wisdom literature's perspective on vanity (Hebrew: hevel - like smoke or vapor) and the fleeting nature of worldly pursuits. Plus, they delve into the beautiful poetry of Hosea 11, where God's parental love and tender compassion shine through despite Israel's unfaithfulness.
