Join Profs. Matt Skinner, Karoline Lewis, and Rolf Jacobson as they explore the lectionary readings for the Second Sunday of Advent, Year A, featuring John the Baptist's prophetic ministry and Isaiah's vision of the peaceable kingdom.

In this episode, the hosts examine John the Baptist's dramatic appearance in Matthew's gospel, styled after Elijah as the forerunner to the Messiah. They discuss why John positions himself in the wilderness, his confrontational message to the religious authorities ("brood of vipers"), and how his call to repentance mirrors Jesus' own first words of ministry. The conversation explores John's anti-establishment stance, his popularity in first-century Palestine, and how his expectations of Jesus differed from the ministry that actually unfolded.

The discussion of Isaiah 11 delves into the promise of a righteous ruler from Jesse's stump and the beautiful poetry of the peaceable kingdom where wolves dwell with lambs and lions eat straw like oxen. The hosts reflect on how this impossible vision confronts the tragic reality of human nature and our inability to solve our own brokenness, pointing to God's solution in Jesus. Karoline highlights the image of righteousness and faithfulness as the very clothing of the Messiah.

The Romans passage brings Paul's climactic call for radical welcome and unity between Jewish and Gentile believers, with Rolf emphasizing the power of blessing as a way God's preferred future breaks into the present moment. The hosts explore two benedictions that offer steadfastness, encouragement, hope, joy, and peace through the Holy Spirit.
