I should have said that those aren’t necessarily the best resources on Romans 9, they just happen to be three I know of. I recommend John Piper’s detailed look at part of chapter. That book really helped my understanding. I also recommend James White’s The Potter’s Freedom, a response to Norman Geisler’s Chosen But Free.

I’m familiar with the Calvinist argument. It contrasts pretty strongly with Scripture. It takes a handful of scriptures out of context and then ignores the hundreds discussing faith and believing.
When Calvin starts discussing God’s secret will, it is obvious he’s gone off track.
