The book of Jude urges us to take sin seriously, both personally and within our community, emphasizing the need to balance love with truth. Without truth, empathy can become enabling and toxic. Jude warns against false teachers, citing the sins of Cain (anger), Balaam (greed), and Korah (dishonoring authority). He also highlights the story of Achan in Joshua 7, where one person's hidden sin caused suffering for all of Israel. Ultimately, God calls us to pursue holiness not just for our own well-being, but for the benefit of those around us.
