Pastor Jeremy Harris emphasized the importance of joy during the Christmas season in his sermon on Luke chapter two, focusing on the song of the angels that proclaimed good news of great joy for all people, especially through the birth of Jesus. He noted that comparison can steal our joy and encouraged the congregation to fix their eyes on Jesus, the source of true joy and peace. Pastor highlighted that experiencing this joy requires faith and action, just as the shepherds acted upon the angel's message to seek out the Savior. Ultimately, he urged believers to share their joy and praises with others as a natural response to experiencing God's goodness and the salvation found in Jesus.
