What does the Bible teach about the universality of sickness?

The preacher notes that sickness is a universal experience for humanity, affecting everyone from the rich to the poor, and serves as a reminder of our mortal condition. The sermon articulates that there is no house that can keep sickness out because all human beings live under the curse of sin. This universality is a crucial teaching in Reformed theology, which acknowledges the fallen state of all creation. Furthermore, sickness acts as a message prompting preparation to meet God, reinforcing the notion that physical suffering ultimately points to deeper spiritual truths.
