What does the Bible say about God's sovereignty over sickness?

Scripture reveals that it is God who has the ultimate control over life and death, health and sickness. As seen in Deuteronomy, it is the Lord who makes sick and who makes alive. In Exodus, when God speaks to Moses, He emphasizes His authority over human conditions, stating, 'Who has made man's mouth? Or who maketh the dumb or deaf or the seeing or the blind? Have not I the Lord?' This authority underscores that sickness is not merely an accident; it is within God's sovereign plan, whether for discipline, growth in faith, or to glorify Himself through healing.
