It does not, therefore, depend on human desire or effort, but on God’s mercy.
For Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.”
Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
One of you will say to me: “Then why does God still blame us? For who is able to resist his will?”

Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?
What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction?
What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory —
even us, whom he also called, not only from the Jews but also from the Gentiles.
