Charles Ellicott Commentary Romans 9:19

"Thou wilt say then unto me, Why doth he still find fault? For who withstandeth his will?" — Romans 9:19 (ASV)

These verses contain the third part of the vindication, which is based on a possible extension of the objection. Not only might it seem as if this absolute choice and rejection was unjust in itself, but also unjust in its consequences. How can a man be blamed or punished, when his actions are determined for him? The Apostle meets this by a simple but emphatic assertion of the absolute and unquestionable prerogative of God over His creatures.
