The topic is election, Cameron.
You are seeking clarification of some verses in Romans 9.
I added two extra verses and let the context speak more clearly.
Romans 9:21-25
Or does the potter not have a right over the clay, to make from the same lump one object for honorable use,
and another for common use? What if God, although willing to demonstrate His wrath and to make His power known,
endured with great patience objects of wrath prepared for destruction? And He did so to make known the riches
of His glory upon objects of mercy, which He prepared beforehand for glory. namely us, whom He also called,
not only from among Jews, but also from among Gentiles, as He also says in Hosea:
“I will call those who were not My people, My people".
A quick explanation because I know where this argument is heading, see below.
Romans 9:30-31
What shall we say then? That Gentiles, who did not pursue righteousness, attained righteousness, but
the righteousness that is by faith; however, Israel, pursuing a law of righteousness, did not arrive at that law.
The clay for 'honorable use' is the Jews and the clay for 'common use' was the Gentiles.
The 'objects of wrath' was everyone, that is, Jews and Gentiles combined.
'Objects of mercy' are those that believe in Jesus and that is by grace through faith.
