First there is the assertion that Calvinism teaches we do not make choices!
Anyone who continues to make this assertion after correction is not only ignorant of Calvinism but willfully so.
Secondly, I raised the Romans passage for hopeful further discussion, but given Haas has tried that many times with little to no response or interaction of the texts he cites, I thought I would start one text at a time and see what transpires.
As far as the assertion that it is not helpful to quote one passage, make a bold statement about it and then stop, well, only a person who knows the future would be able to say that with any seriousness.
I have no intention of just stopping!
Then there is this statement
What is being said here besides nothing of any substance, not to mention, how could such an answer end up causing Paul to defend the free will of God a few verses later?9:18
Therefore He has mercy on whom He wills, and whom He wills He hardens.
This should say enough, but let me expound.
God has mercy on those we wills (believers), and He will not have mercy on those he does not will (un-believers). those un-believers are left to the hardness of their own heart.
No! Paul is teaching that God is totally free in whom He saves and none of it depends upon the free will of man!
That is why Paul has to deal with the following response, which honest Arminians themselves have often said to me personally,
Rom 9:19 You will then say to me, Why does He yet find fault? For who has resisted His will?
You all know the next verse!
Also, if believers were once unbelievers, how does the above statement help us in any way?
Notice what is not being said in the above statement but implied!
Things like libertarian free will still tenatiously clung to as if the difference between the believer and the unbeliever is not God's grace and choice, but the free will of man.
That is boasting!
What else could it be called if the difference between me and my unbelieving neighbor is my decision to accept Christ?
Arminians who are honest should own the question which Paul answers above, or at least think through afresh, their theology.
You can go to other passages that have been answered, but why?
Let us camp here in Romans 9 for a while and see what transpires.
Mark
