What is he talking about? "That which Elohim (God) hath foreordained (the sovereignty of Elohim/God) you with wicked hands have taken and crucified (the responsibility of man)." Peter holds it in tension.
The apostle Paul in Philippians 2:12 does the same thing. He says:
"Work out your own salvation (the responsibility of man), for it is Elohim (God) that worketh in you both to will and to do of His good pleasure (the sovereignty of Elohim/God)" (Phil.2:12, KJV).
So Paul holds it in tension. Yah'shua (Jesus) also in Matthew 18:7 says:
"Offenses mustcome, but woe unto him through whom they come (the sovereignty of God and responsibility of man)" (Mt.18:7, KJV)
So in an attempt to try to clearly highlight either of these two extremes, you will do violence to the other. In your example of Romans 9, it is imperative that you understand the context. In Romans, chapters 9, 10 and 11, Paul is primarily writing to the Judahite (Jewish) messianic community (church) in order to get them to understand that the chosenness that Elohim (God) had given to them was a privilege with concomitant responsibilities. He goes on to show that their privileged position was given to them because someone had to be a mouthpiece to the world and Elohim (God) chose the least of all the nations. He did not choose the philosophers in Greece; He did not choose the imperial might of Rome; He did notchoose the splendor of Babylon. He chose a tiny little nation with whom and through whom He was going to pronounce the oracles to the rest of the world. Now, with that great privilege came a proportionate responsibility. So that chosenness was one of instrumentality, and to whom much was given much was also required.
In the same way, I believe this principle applies to preachers. Just because we are called upon to stand in front of people and proclaim, it does not necessarily mean we have a better deal going for us. The fact is that our lives must be proportionate to the privilege and responsibility. The passage in Peter expresses Elohim's (God's) desire for all mankind. Of course, He is not willing that any should perish.
Now, what you need to do is recognise that foreknowledge and foreordination are not the same thing. I may know, for example, that as I see my child about to lift something heavy that he is not going to be able to lift it, but there are times when I stand back and watch in an attempt to teach this individual the fact that there are some loads too heavy for a smaller body to handle. Now when you are looking at the sovereignty of Elohim (God), it is undeniable that Elohim (God) is sovereign in history. He is even able to take the evil intents of people and turn them around to good benefits. But isn't that true of all life?
There are some things in life that are givens -- you and I have no control over them, but we do have options as to how we are going to deal with those givens, and that is where our responsibility comes in. When you think of the mystery of sovereignty and responsibility, the very incarnation of Messiah carries this enigma. Here is the sovereign Elohim (God) dwelling in a finite body with all of its limitations.
So in my initial answer to you, may I suggest that you look at these two points as opposite poles of a dialectic; we cannot take Elohim (God) and put Him in a box as absolutely free. Somewhere the sovereignty of Elohim (God) and the responsibility of man meet. The picture I have in mind is not of overlapping circles, as if each circle represented one extreme of the pole, but of conjoining circles. At some spot the sovereignty of Elohim (God) and the responsibility of man meet. To try to answer it and explain it away would require infinite knowledge.
The challenge you and I face, therefore, in life is to see how we can responsibly operate within the parameters that are so clear -- Elohim (God) is sovereign, and yet I have the freedom and reserve the right to say yes or to say no.
You see, Elohim (God) has given to every man the fundamental privilege of trusting Him or refusing to trust Him. You know, the old illustration used to be the sign outside of Heaven saying 'Whosoever will may come', and once you enter in, you see the sign that says, 'Chosen before thefoundation of the world'. A person who is truly born again recognises that it was really the grace of Elohim (God) that brought him there because he could never have come this way himself.
It does not in any way mitigate or violate the choice that he made. The choice man makes is to trust Elohim's (God's) provision. Frankly, the tendency we may sometimes have is to complain that there is only one door to Heaven. Rather than complaining about it, we ought to thank Elohim (God) that there is at least one door by which we may enter. There have been Calvinists and Arminians, giants of the faith, on both sides of the fence. I believe what John Calvin says holds very true:
My own perspective on this is that Elohim's (God's) assurance of sovereignty is given to the person who wonders whatever caused him to merit the salvation, and Elohim's (God's) challenge of free will is to the person who tends to blame Elohim (God) for having even brought him into this world and that he has nothing to do to control his destiny.
When you look at the encounter between Pharaoh and Moses, you see the constant availability of data given to Pharaoh, and the hardening process is really not a predestined one. It is a description after the fact that Elohim (God) was going to reveal the face that this man's heart was already hardened. Remember, Elohim (God) operates in the eternal now.
So to sum up once again, the chapters of Romans 9, 10 and 11 are Paul's theological treatise to the Judahites (Jews) to alert them to the fact that this great privilege does not let them get away scot-free. They have an enormous and a proportionate responsibility. He goes on to alert other nations that, rather than complaining about it, they should be glad that a privilege was given to someone, and through that someone this message has come to them also. In fact, if you read Romans 1, 2 and 3, you will find out that the privilege that the Jidahite (Jew) had, in many ways, for many of them, turned out to be a disadvantage. If you read Romans 5, you will find out that even though Elohim (God) called Abraham, it was the faith of Abraham that justified him. Once again you see the sovereignty and responsibility. Why don't we leave this enigma within the divine mind and just be grateful for the privilege that we have heard His voice and we can turn and follow Him?
May I strongly recommend that you pick up the book written by J.I. Packer, Evangelism and the Sovereignty of God. His introductory comments alone, dealing with the difference between a contradiction and a paradox, are well done. If Elohim (God) were absolutely sovereign, then it would be a contradiction to say that man is absolutely
free. Elohim (God) is not absolutely sovereign to the point that He can call something that is not as if it actually were.
For example, Elohim (God) cannot make squares into circles. That would be a contradiction. So absolute sovereignty is really not what is being talked about here. Elohim (God), therefore, has chosen to give us the option and, within that framework, He cannot call us free while absolutely violating that freedom. Both poles exist -- His sovereignty and our responsibility. We rest on the fact that Elohim (God) is just, that Elohim (God) is love, that Elohim (God) is good, and He woos us enough so that we may trust Him and yet gives us enough freedom so that we might know that this freedom cannot be transformed into coercion.
