Romans 9:11-18

9:11 even before they were born or had done anything good or bad (so that God’s purpose in election would stand, not by works but by his calling) – 9:12 it was said to her, “The older will serve the younger,” 9:13 just as it is written: “Jacob I loved, but Esau I hated.”

9:14 What shall we say then? Is there injustice with God? Absolutely not! 9:15 For he says to Moses: “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” 9:16 So then, it does not depend on human desire or exertion, but on God who shows mercy. 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.
