Romans 9:18-20 Revised Standard Version (RSV)
18 So then he has mercy upon whomever he wills, and he hardens the heart of whomever he wills.
God’s Wrath and Mercy
19 You will say to me then, “Why does he still find fault? For who can resist his will?” 20 But who are you, a man, to answer back to God? Will what is molded say to its molder, “Why have you made me thus?”
