14What then shall we say? Is God unjust? Not at all! 15For he says to Moses,
"I will have mercy on whom I have mercy,
and I will have compassion on whom I have compassion."
16It does not, therefore, depend on man's desire or effort, but on God's mercy. 17For the 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." 18Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
19One of you will say to me: "Then why does God still blame us? For who resists his will?" 20But who are you, O man, to talk back to God? "Shall what is formed say to him who formed it, 'Why did you make me like this?' " 21Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?
