How is is possible for Pharaoh to have repented and allowed Israel to depart in peace, if he was raised up for this purpose?
God actively hardened Pharaoh's heart that he might judge e.g. "lay his hand upon" Egypt. Could Pharaoh have overcome God's hardening of his heart? How?
There is no question that Pharaoh hardened his own heart as is indicated in Ex. 8:15,32. Pharaoh is a responsible moral agent, but this doesn't answer the question of whether or not it was possible for Pharaoh to soften his own heart and repent despite God's will?The king's heart is in the hands of the LORD, as the rivers of water, he turns it whithersoever he will Proverbs 21:1
If Pharoah had repented of his sins and turned Israel free, how could God's word have been fulfilled?
Is it possible for sinful or even righteous man to thwart God's declared intent?
If he did this to Pharaoh, why wouldn't he do it to the rest of rebellious humanity?
