Yes. Its all good.
Romans 9:14-24 (ESV)
What shall we say then? Is there injustice on God's part? By no means! For he says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion." So then it depends not on human will or exertion, but on God, who has mercy. For the Scripture says to Pharaoh, "For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth." So then he has mercy on whomever he wills, and he hardens whomever he wills.
You will say to me then, "Why does he still find fault? For who can resist his will?" But who are you, O man, to answer back to God? Will what is molded say to its molder, "Why have you made me like this?" Has the potter no right over the clay, to make out of the same lump one vessel for honored use and another for dishonorable use? What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory — even us whom he has called, not from the Jews only but also from the Gentiles?
1) Paul is addressing a question of injustice on God's part. How does the objection raised here ("Why does he still find fault? For who can resist his will?") differ from your objection to condemnation without ability?
Good Question: First I will deal with the objection of Injustice:
THE JEWS OBJECTION: The Jew would be objecting to Paul's message because according to Paul God is showing mercy to dirty Gentiles and he is hardening the "chosen" seed of Abraham, the Jews. This is the objection of injustice in Romans 9.
MY OBJECTION: It brings reproach upon God to invite all men without granting all men the ability to respond and then judge them for that response on the final day. It is unjust to hold a man responsible when he is not response-able.
Now, the objection of finding fault and resisting his will:
THE JEWS OBJECTION: If God were to say, "I will show mercy to whom I please, even dirty Gentiles, and I will hardened whom I please, even the Jews. The Jew, who has been hardened, would object to being hardened by saying, "Then why does he still find fault? For who resists his will?" (NOTE: The Jew has been hearing and yet rejecting the revelation of God for years as God has patiently held out his hands to them all along (Rom. 10:21) and has longed to gather them under his wings of salvation (Matt. 23:37). But they, for the most part, have rebelled from His revelations, thus they were hardened. But this hardening is not unto certain condemnation, for if you read Romans 11 you will see that the ingrafting of the Gentiles will provoke the hardened Jews to envy so that they might be saved as well (vs. 14) for God bound them over to disobedience so as to have mercy on them (vs. 30-32) not to condemn them.)
MY OBJECTION: I object to a dogma that teaches men are born hardened to the point that they never are capable of hearing and responding in faith to God's revelation. See the difference? Romans 9 is teaching that rebellious men who have continually heard and refused the truth are being temporarily hardened so that they might be provoked and saved. Calvinism teaches that men are born hardened (depraved) having never had the opportunity to even understand or respond in faith to God's revelations and this hardening is unto certain condemnation.
2) Some vessels are prepared for mercy leading to glory, but others for destruction and wrath (not temporary hardening).
Romans 11 refers to the hardening as temporary and certainly shows it is not certainly unto condemnation in verse 14 and 30-32. The "vessels of mercy" are those who believe, whether from the Jews or the Gentiles. The vessels of wrath who fitted themselves for destruction despite God's longsuffering is a reference to the Jews who are now being hardened.
3) The vessels prepared for glory include both Jews and Gentiles.
Agreed, but Paul is pointing to the unaccepted fact that the Gentiles are among these vessels being prepared.
4) The question of whether God is unjust for creating anything expressly for the purpose of pouring His wrath out upon it is dismissed.
That is your error. You think this passage is about God creating men for the purpose of pouring out his wrath upon them. The wrath is being poured out upon those who God held out his hands to (Romans 10:21) and who he desired to gather under his wings (Matt. 23:37) and that wrath can still be avoided if they don't continue in their unbelief (Rom. 11:23). God bound all men over to disobedience so as to show them all mercy, not so as to pour out his wrath. (Rom. 11:30-32)
