Exodus 9:13-16

God was going to use Pharaoh to proclaim His name in all the earth. That was God’s plan, and nothing was going to stop it. Pharaoh however got to decide how he would be a part of God’s plan. He could humble himself before the Lord and declare to the world that “The Lord is God”. Or he could defy the Lord God in which God’s acts of judgment would become Pharaoh’s testimony. God’s purposes cannot be stopped - we just get to decide what role we play in God’s story.
