Romans 9:17-19

17For the scripture says to Pharaoh: “For this very purpose I have raised you up, that I may demonstrate my power in you, and that my name may be proclaimed in all the earth.”

18So then, God has mercy on whom he chooses to have mercy, and he hardens whom he chooses to harden.

19You will say to me then, “Why does he still find fault? For who has ever resisted his will?”
