What should Christians learn from Pharaoh's hardened heart?

Pharaoh's hardened heart is a sobering example of what happens when one refuses to listen to God's warnings and reject His truth. Despite witnessing miraculous signs and wonders, Pharaoh continued in rebellion against God, leading to greater judgment. This reflects the biblical principle that rejecting God's revelation can lead to a continued hardening of one’s heart, making repentance increasingly difficult. For Christians, this is a call to remain sensitive to the Holy Spirit’s prompting and to respond to God's gracious calls to repentance without delay.
