What does the Bible say about Pharaoh's hard heart?

In Exodus, we see Pharaoh's heart hardened against God as a direct response to the Lord's command through Moses. This signifies a profound spiritual truth about humanity's nature; we are often in total opposition to God, symbolized by Pharaoh's hard heart. As Romans 3:10-11 states, 'There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God.' Pharaoh's hardened heart ultimately leads to God’s judgment, demonstrating the severe impact of sin and rebellion against divine authority. This narrative serves as a warning about the consequences of a heart that resists God’s will.
