But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in the land of Egypt, Pharaoh will not listen to you. Exodus 7:3
Pharaoh will not listen to you, that my wonders may be multiplied in the land of Egypt. Exodus 11:9

Give thanks, today, for what seems like a prolonging of God's plan. A perfect, pre-determined presentation of His power is the point!

HOLD. ON.
