Brother, in your quest to stamp out Calvinism (which you, nor anyone, will ever do) you are going to an extreme that just isn't true.
This has nothing to do with Calvinism, R.C. Sproul is absolutely a Calvinist, yet he believes Jesus could have sinned. That doesn't prove anything, I am just showing this is not an Arminian versus Calvinist debate.
This debate is whether Jesus truly came in the flesh and was completely human. If so, then he could have sinned. I believe Jesus actually implied he could sin and I showed the scripture to back this up. It also seems nonsensical to tempt Jesus if he could not sin. What kind of test is that?
You are trying to stress to us that God could fail in Jesus Christ, then you go to Jacob and try to prove that God did fail with Jacob.
All I can say is what the scriptures say, and they clearly say Jacob PREVAILED. This is a very simple and straightforwad story, very easy to understand.
What was Jacob's conclusion? Did Jacob believe he defeated God? Jacob said, "I have seen God face to face, and my life is preserved." Hardly a victory cry.
Yes, I believe Jacob did understand he prevailed, and he demanded that God bless him before he would agree to let God go. And that is exactly what God did.
And what was the lesson for Jacob? God said, "for as a prince hast thou power with God and with men, and hast prevailed." As you can see, it does not say Jacob hast power OVER God.
It said Jacob had power WITH God and had prevailed. Prevailed means he won, he overcame. You can't ignore the word because you don't like it.
I believe the lesson is faith and to persist in prayer. Jesus told a similar story of a judge who feared no one, not even God. This woman had to persist to finally get her way with this judge. I believe this is what is being shown, Jacob was not going to give up until he got a blessing from God. This is a lesson to us to persist with God in prayer.
Luk 18:1 And he spake a parable unto them to this end, that men ought always to pray, and not to faint;
2 Saying, There was in a city a judge, which feared not God, neither regarded man:
3 And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary.
4 And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man;
5 Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.
6 And the Lord said, Hear what the unjust judge saith.
7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?
Many here have a false view of God. To many here God is just this gigantic supreme tyrant. He is made of stone and does whatever he wants with no regard to anyone.
This is not what scripture shows. Scripture shows God can be appealed to. If we continue to pray and pray, God will listen to our prayers, and oftentimes grant our requests if they are not sinful. Like a loving parent, God wants to give good things to his children when they ask. God is not made of stone, he is loving and patient. He is not interested in his glory only as many here falsely teach. He loves his children and is concerned with their needs.
And this is the story of Jacob, he wrestled with God. He would not give up, he demanded that God bless him, and he got his request.
