Romans 9:11-16

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.

Romans 9:21

9:21 Has the potter no right to make from the same lump of clay one vessel for special use and another for ordinary use?
