In this sermon, the preacher focuses on Isaiah chapter 5 and the judgment of God. He describes the judgment using three images: fire, a rotten root, and a blossom that vanishes. The preacher emphasizes that there is no salvation in this passage, only judgment. He urges the listeners to flee from the wrath to come and to believe in the gospel, asking God to help them learn how to sing and to see His loving kindness. The sermon also highlights that God's love sometimes expresses itself through judgment.
