Why Did God Harden Pharaoh's Heart?
Exodus presents God's sovereignty and Pharaoh's culpable resistance together. A careful reading must account for the whole sequence of the narrative.
Follow the repeated language
Different Hebrew descriptions are used across the plagues, including making firm, making heavy, and making hard. The narrative also alternates between Pharaoh's actions and God's judgment.
Sovereignty and responsibility
The text does not reduce Pharaoh to a passive victim. Pharaoh repeatedly resists, refuses, and hardens his own heart, while God confirms his judgment and displays his power.
Where traditions differ
Christian traditions explain the relationship between divine sovereignty and human responsibility in different ways. Responsible interpretation should represent those differences without pretending the passage answers every later debate in the same vocabulary.
