St. Augustine's "City of God"

St. Augustine's "City of God" is a philosophical work that contrasts two types of communities: the earthly city, rooted in self-interest and material pursuits, and the heavenly city, guided by divine love and spiritual values. Augustine argues that true peace and happiness come from aligning one's life with God's eternal plan, rather than worldly desires. The book reflects on history, spirituality, and morality, emphasizing that Christians should prioritize their spiritual relationship with God over worldly concerns, ultimately shaping their hope for eternal life in the heavenly city.
