In his sermon, Shawn emphasizes the contrasting images of power depicted in the book of Revelation. He highlights the significance of the slain Lamb, representing Jesus, who holds true power and authority, countering the oppressive power of Rome faced by early Christians. Shawn encourages believers to align themselves with Jesus, rather than the fleeting influences of the world, and to remain steadfast even amid trials and persecution. He concludes by reminding the congregation that ultimate victory belongs to the Lamb, urging them to live faithfully and courageously in light of this truth.
