Thomas Brooks emphasizes the dangers of luxury as a sin that is particularly prevalent in society, warning that it is a God-dishonoring and soul-damning behavior that can lead individuals away from salvation. He cites biblical examples, such as the rich man in Luke, to illustrate that those who indulge in luxury are often far from true repentance and faith in Christ. Brooks argues that luxurious living is incompatible with the teachings of Jesus and suggests that such individuals may not genuinely be Christians. He highlights the rarity of reformation among the luxurious, contrasting their lifestyle with the call to holiness and self-denial. Ultimately, he warns that a life of luxury leads to spiritual ruin and separation from God.
