John Gill expounds on 2 Peter 2:10, emphasizing the dangers of those who walk after the flesh, particularly in the context of immoral practices that defy both natural law and divine authority. He warns against the pride and rebellion of individuals who despise governance, whether it be familial, civil, or divine, leading to chaos and sin. Gill highlights the severity of judgment that awaits those who engage in such behaviors, noting their presumptuousness and self-willed nature, which leads them to speak against dignities and authorities. The sermon serves as a stark reminder of the consequences of rejecting God's order and the moral decay that follows.
