Hi Jarthur001
First I apologize for misunderstanign your question.
--------------------------------------------------
You asked........
“What does the word hate mean in Romans 9?”
I feel you are being kind of cryptic here, but.......
“Hate” Lit. (miseo) “To pursue with hatred!”
--------------------------------------------------
But then you went a little deeper with.......
“Also...you choose to go to another passage to find the reason for that hate. Yet does not the passage in Romans 9 tell us why, so that we need not guess why?”
Now you seem to asking, “why God hated Esau”? (Not “what does hate mean”.)
--------------------------------------------------
Therefore, I can only guess what you are getting at:
But here is one of my favorite verses.....
Romans 9:11
“(For [the children] being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth

”
I love the point being made here, because I love God’s Grace.
The fact is, anyone who gets saved, must be elected, in order for there salvation to be by Grace.
If anyone, could ever save themselves, than Christ would not have had to die on the cross.
(Salvation is totally of God!)
--------------------------------------------------
Then you continue with........
“Also..you used Romans 8...(if I recall right)...to give reason for Romans 9. You take the old "foreknow" path. I asked before and I ask again.....just who did God foreknow? In other words, did God look and know if Cain would believe or not, and base election on what he saw? This is your claim what happen in Romans 9"
Now here is your main question.......
“Just who did God foreknow?”
I think this is where you and I will really part company.
God foreknew everyone.
(Now I think you Calvinists, limit God’s foreknowledge, to only the elect, but I don’t.)
Because of God’s Omniscience. (God can’t help, but to have known the future decisions, of everyone.)
Yes, God foreknew, Esau.
(And before you say it, yes I do know what “know” means.)
And I believe, that God knows absolutely everything about everyone that will ever be born..
Matthew 10:30
“But the very hairs of your head are all numbered.”
--------------------------------------------------
Now for the first part of your response........
“Do you not see Calvinism all the way through this passage?
God intended to send the gospel a place, he gave a special direction to Philip to go and convey it. It is evident that God designed the conversion of this eunuch, and the direction to Philip shows how he accomplishes his designs. It is not by miracle, but by the use of means.
It is the power of God in Salvation. When a sinner is converted, it is because God forms a plan or purpose to do it. When it is done, he inclines his servants into action. God directs their actions. He leads his ministers to the place they should be and he prepares the way for the reception of the truth.
Now think with me here. We are not told why the eunuch took up the reading of the Bible. I would say it was the plan of God and Him working in his life. But...going by the very words of the eunuch, would the eunuch have become a believe, if God had not sent someone? he said he did not understand...and wonder how any one could understand.”
No, I don’t see Calvinism in this: What I see is someone using the light God has already given him, and seeking for more light.
If the eunuch would have not been interested in learning more about God, than God would not have sent Philip to him.
What we have here, is a “chicken and the egg” disagreement.
--------------------------------------------------
I believe the Bible teaches, that everyone will have an opportunity to get saved.
And if you take that opportunity, than God will arrange for you to receive more information.
But if your reject that opportunity, than God will allow your to reject it, and allow you to fall into more Spiritual darkness.
(As we see in Romans 1

--------------------------------------------------
I just realized, what Calvinism and Arminianism have in common:
(They both believe that some people, will not have an opportunity to get saved.)
(1)Calvinism: (Says the non-elect, will have no chance to get saved

(2)Arminianism: (Says that those who don’t here the Gospel, can’t get saved
While we Biblicist, believe that everyone will have an opportunity to get saved!
(1)(Even if your not elected, you must be given a fair chance to get saved

(2)(Even if a soul winner doesn’t come to where you are, you will find one!)
