The sermon explores the pervasive nature of toxicity within the church, emphasizing that even good people can unintentionally cause harm through unrealistic expectations, unresolved issues, misunderstandings of scripture, fear of change, and a lack of maturity. Drawing from 1 Corinthians 10 and Psalms 133, the message underscores the importance of unity and encourages listeners to cultivate emotional and spiritual maturity, actively seeking resolution and open communication to foster a supportive and unified community, while also presenting the gospel to those who are lost and seeking a relationship with Christ.
