The sermon emphasizes the importance of cultivating a healthy church by embracing both positive actions and avoiding detrimental behaviors. Drawing from Titus, it highlights the need for submission to authority, demonstrating kindness, and appreciating the transformative power of the gospel, which stems from God's mercy and the sacrifice of Jesus. Conversely, it cautions against engaging in frivolous disputes, rejecting divisive individuals, and ultimately, striving for a life of godliness motivated by gratitude for salvation and a hopeful anticipation of eternal life.
