What does the Bible say about Pharaoh's defiance against God?

Pharaoh's defiance against God encapsulates the essence of human rebellion against divine authority. In Exodus 5:2, Pharaoh arrogantly questions, 'Who is the Lord that I should obey his voice?' This response illustrates not an ignorance but a willful defiance, a hallmark of the unregenerate heart. Like Pharaoh, we too are born in a state of resistance; our default condition is one of hostility towards God's claims. Such defiance is not unique to Pharaoh; it is shared by all humanity apart from divine intervention. The sermon highlights that just as Pharaoh hardened his heart (Exodus 7:3), we also, by nature, resist the truth unless God grants us a new heart to perceive and obey Him.
