What does the Bible say about God's sovereignty in Joseph's story?

In Genesis 41, Joseph repeatedly attributes the dreams of Pharaoh to God, making it clear that it is the Lord who determines the times of plenty and famine. Joseph insists to Pharaoh that the dreams he has were divinely ordained, stating, 'God hath shown Pharaoh what he is about to do' (Genesis 41:25). This underscores the doctrine of God's sovereignty, revealing that He is in control of all circumstances to fulfill His purposes, even using the actions of those opposed to Him. The events in Joseph's life serve to demonstrate God's overarching plan for His people, establishing His covenant promises displayed through the lineage of Abraham and culminating in the salvation narrative found in Christ.
