What does the Bible say about sickness and sin?

According to the sermon, sickness is a consequence of the Fall, where Adam's disobedience brought sin and death into God's perfect creation. The initial goodness of creation was marred by this disobedience, resulting in sickness being a universal experience for all, regardless of status. While not every sickness results from a specific personal sin, its existence serves as a reminder of humanity's fallen nature. This theological perspective emphasizes the need for spiritual preparation, highlighting that all must one day stand before God.
