Romans 9:18-20 New International Version - UK (NIVUK)
18 Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
19 One of you will say to me: ‘Then why does God still blame us? For who is able to resist his will?’ 20 But who are you, a human being, to talk back to God? ‘Shall what is formed say to the one who formed it, “Why did you make me like this?”’[a]
