In the Bible, we first encounter God when he sides with a bunch of slaves against a powerful Pharaoh, an act of grace freely given.
- Desmond Tutu
All that God had to do to harden Pharaoh's heart, or to harden your heart, is to withhold His own grace.
- RC Sproul
In the Bible, God offered the Pharaoh freedom if he would just let the oppressed people free to go to the land of milk and honey. But the Pharaoh disobeyed, and he was destroyed.
