The sermon explores the origin of suffering, focusing on selfishness as a key contributor. Drawing from Genesis chapter three, it examines how Satan's deception and the temptation of Eve, rooted in self-will and disregard for divine instruction, initiated a pattern of suffering that continues to impact humanity. The speaker emphasizes that selfishness, manifested in various forms throughout history and present in contemporary society, is a direct consequence of Satan's lies and a rejection of God's will, ultimately producing pain and devastation while highlighting the importance of understanding these origins to navigate the complexities of suffering.
