For that matter, not even counting things he says in subsequent chapters, Paul INSTANTLY goes on to say that his fellow-countrymen about whom he has unceasing grief in his heart still have the promises of the covenants and the adoption as sons. And this is despite them not being Israel spiritually yet, only Israel by physical descent: because it isn’t by (mere) physical descent by which people are children of Abraham, but by the promise of the Abrahamic covenant – yet the Son Who stands for Abraham in making the covenant of the promise with the Father, that Abraham’s children through Isaac shall number ridiculously large and shall all be brought to righteousness and so all the nations of the world shall be blessed? He descends physically through Isaac not through Ishmael, and through Jacob not Esau. But God has mercy and compassion on whomever He chooses without merit or demerit for that matter, even if He hardens their heart for a time as with Pharaoh whom God promised to raise up for leading the nations to worship God. (Probably referring to rabbinic theories about why this promise seems to fail when Pharaoh dies soon afterward: it didn’t fail, God raised him up from death on one or the other side of the Sea, and then he did this or that which led people to worship God.)
After which Paul immediately cites one or more of the places where God promises to restore Israel after punishing her because He still loves her, and rebukes those who think God has abandoned Israel forever to punishment. And so on.
Soooo… yeah, not a hopeless punishment situation, much less not a situation where some are elected to be saved from sin and God chooses not to elect others to be saved from sin. But some are elected to be vessels of mercy, i.e. for pouring out mercy, just like others are elected to be vessels for pouring out destruction and yet God expressly has {makrothemia} for them: the term which Calvinists recognize to be the intention of God to save sinners from sin, which we had better not despise for God shall certainly succeed in doing so!
(Ironically, though quite properly, they cite 2 Peter among other places for that, where Arminians just as properly cite testimony nearby that God intends everyone to be saved from sin.)
