Rom 9:10-16
"And not only so, but also Rebekah’s children were conceived at the same time by our father Isaac. Yet, before the twins were born or had done anything good or bad—in order that God’s purpose of election might continue, not because of works but because of his call—she was told, 'The older will serve the younger.' As it is written, 'Jacob I loved, but Esau I hated.' So then it depends not on human will or exertion, but on God, who has mercy."
The election of Jacob over Esau before birth—without regard to works—proves that divine election is not based on human merit. God’s sovereignty in election is not arbitrariness—it is mercy beyond what we deserve.
Rom 9:20-21
"But who are you, O man, to answer back to God? Will what is molded say to its molder, 'Why have you made me like this?'"
The potter metaphor (Isa 29:16; 45:9; Jer 18:1-10) teaches that God has the sovereign right to use His creatures as He pleases. Paul’s response to the objection is not a philosophical explanation—it is a reorientation: who are we to question the Creator?
