Romans 9:17-19

9:17 For 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.” 9:18 So then, God has mercy on whom he chooses to have mercy, and he hardens whom he chooses to harden.

9:19 You will say to me then, “Why does he still find fault? For who has ever resisted his will?”
