Romans 9 is discussing the Jewish nation, not an individual man. Although individual Jews did believe, Paul discusses why the NATION did not.

None of which negates the depravity of man and our need for a savior.
The whole is made of parts.
If one person sins; then the whole nation does.
Get rid of that person that drags you down.
Really? I don’t want to debate you on the, but I hope you will consider these. For decades I would have agreed with you. In fact, I used to argue the exact same thing. Understanding God’s sovereignty in salvation changed my life.

Except verses 22-24 make it clear the whole analogy is about individuals (vessels of mercy) and is not just about Israel. The whole point of the passage is salvation was NEVER about the nation, and God always chose individuals - Isaac rather than Ishmael, Jacob rather than Esau, Moses rather than Pharaoh. Some who are "of Israel" are Israel and some are not. In the same way, he chooses individuals (both Jews and Gentiles) for salvation now.
Romans 9:22-24 22 What if God, wanting to show His wrath and to make His power known, endured with much longsuffering the vessels of wrath prepared for destruction, 23 and that He might make known the riches of His glory on the vessels of mercy, which He had prepared beforehand for glory, 24 even us whom He called, not of the Jews only, but also of the Gentiles?
