Jude, the younger half-brother of Jesus, emphasizes the importance of recognizing sin for what it is in his letter. He reminds us that Jesus, our Savior and Judge, offers mercy while holding those who reject it accountable for their sins. Jude warns against various sins that people attempt to normalize, and Pastor David highlights modern sins that society often overlooks. Acknowledging these sins is crucial for moving toward the greater life that God offers us.
