God hardened Pharaoh's heart to demonstrate His power and bring glory to Himself through the salvation of Israel (Exodus 14:4).
The hardening of Pharaoh's heart serves a dual purpose in the narrative of Exodus. First, it highlights God's sovereignty over human decisions and serves as a mechanism through which God reveals His glory. God's declaration in Exodus 14:4 explains that He hardened Pharaoh's heart so that Pharaoh would chase after the Israelites, ultimately leading to their deliverance and demonstrating God's power over Egypt. Furthermore, this act illustrates God's righteous judgment, as Pharaoh's heart was already predisposed to reject God's authority. Therefore, the hardening of Pharaoh's heart is not only a demonstration of God's theocentric plan but also a stark reminder of His justice in dealing with rebellion against Him.
