Honest struggles on God’s omniscience.

[way 2 go]

Why was that necessary if he had already been declared righteous? (Gen 15:6, as you pointed out)

Abraham received a saving act of grace by God and was faithful thereafter

And he was already known to be faithful extending to his family? i.e., it didn't appear to be because of the interrupted sacrifice of Isaac that Abraham was faithful thereafter.
Genesis 18:19 KJV — For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.

verse showing God's foreknowledge
Genesis 18:19 KJV —

So if there's no gain for eather God or Abraham, why go through it at all?

Abraham received a saving act of grace by God and was faithful thereafter

Rather it was part of a process of God testing Abraham, first to leave his homeland, then to trust for a new home, then to trust for a child-heir (from Sarah), then to trust for God's provision no matter what (he was confident that God could raise him from the dead, even:
Hebrews 11:19 KJV — Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
But not at first. Abraham was not that trusting at first. He didn't think God could give him a child by Sarah. So the testing came over 25 years until Isaac was born, then another bunch of years (unspecified, but I'd propose 15) until the almost sacrifice.

so not testing God

we the readers have God prophesying his own sacrifice for the sin of the world scape goat and all.

(Romans 4:16) Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,

Did God do this for Abraham's gain or God's? Why not both? Abraham grew in knowledge of God, why can't God grow in knowledge of Abraham? Isn't it only because you have already decided that God already knows all future things based on other verses that don't require it?

Abraham grew in faith , God already knew ,Genesis 18:19

(Job 21:22) Shall any teach God knowledge, since He shall judge the exalted?
(Romans 11:34) For who hath known the mind of the Lord? or who hath been his counsellor?

verse showing God's foreknowledge

Again, you can't seem to understand the difference between "foreknowledge" and "EXHAUSTIVE foreknowledge".

They are NOT the same.

NOW I KNOW means something.

Gen 22:12 (AKJV/PCE)​

(22:12) And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only [son] from me.​

Imagine a man who has known his best friend for many years. He knows his friend deeply — his character, his habits, and especially that he loves to bluff in poker.One day they sit down to play. His friend goes all-in with a terrible hand. After the cards are revealed and the bluff is exposed, the man says, “Now I know you love to bluff.”Would we understand this to mean the man just learned that his friend likes to bluff? Of course not. He already knew it. His statement “Now I know” is not a declaration of new knowledge, but a public confirmation and demonstration of what he already knew to be true.In the same way, when God says to Abraham in Genesis 22:12


After David committed adultery with Bathsheba and had Uriah killed, God sent the prophet Nathan to confront him.Nathan did not walk in and say, “You committed adultery and murder.”
Instead, he told David a story about a rich man who stole a poor man’s only lamb. David became outraged and said the rich man deserved to die. Then Nathan delivered the blow:

(II Samuel 12:7) And Nathan said to David, Thou art the man.

then God's judgement came

God knew what David had done and foreknew that David would incriminate himself
God exposed David’s sin in a way that would lead to genuine conviction and repentance also let David’s own sense of justice condemn his actions.

@way 2 go You're going to believe whatever you want to believe. You are impervious to evidence or arguments against your position. You know nothing about the view that opposes yours and you like it that way. Enjoy your ignorance.

... [God foreknew that David would incriminate himself] ...

Agreed. When you subject this passage to the same scrutiny Open Theists subject "Now I know" to, the necessary inference is that God foreknew that David would incriminate himself. That was obv the setup. God knew that David wouldn't detect that it was a setup, and David didn't, he walked right into it. God knew David was going to do that. Same scrutiny applied to "Now I know" means that God foreknew David would walk right into it in "Thou art the man".

Carrying over from Fidderent Stuff

Lol! I call that the "door/window fallacy", not because anyone else in the whole world would recognize the term, but because when my kids were little, they would argue like that, and I tried to show them what it was like by imagining two people arguing, one pointing to the door, saying, "That is a door," while the other points at a window and says, "No, that is a window," followed by the first replying, "No, that is a door," still pointing at the door. Neither were wrong, except when included the word "No," and didn't pay attention to where the other was pointing.

Agreed

Remember that God said He would harden Pharaohs heart before Moses ever left Midian...
Exodus 4:21 KJV — And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.

... therefore anything He said could not have been based on interactions in the past between them. But God must have been "searching Pharaoh's heart" to determine the best way to free the Israelites (400 years were previously mentioned to Abraham).

Yes, but God knew about Pharaoh specifically, and had to to know that he wouldn't be one of the few that wouldn't double down.

I agree, and I've always agreed, and this is why I constantly advise that you should watch¹ The Game with Michael Douglas and Sean Penn, because this is the whole premise of the movie. You can do what is indistinguishable on paper from predetermining and foreordaining, if you know a guy well enough.

¹ IF you're an adult AND you're not tempted by modern movies and television programming²
² Nothing notably smutty that I remember, but apparently per Lon²ᵃ there's coarse language³

³ I'm not wanting to break TOL rules against implied profanity​

First, did He already know the answer to the question He posed, "Will ye also go away?"

[At the time He asked the question? Maybe.]

If He didn't know the answer to the question when He asked it the whole interpretation of the scene is different to me and conflicts with how I've always understood it, all the way from my youth. I'm OK with such traumatic shifts in how I read the Scripture. I can countenance the possibility as I hold it in my mind and observe it, and its logical outcroppings, implications, and entailments. So my estimation of whether He already knew the answer to the question before He asked it or as He asked it, isn't coerced. It's just a question of consistency and coherence. I think that He did know the answer when he asked the question. I think He knew what Peter would say.

$$ Joh 6:68
Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
$$ Joh 6:69
And we believe and are sure that thou art that Christ, the Son of the living God.

If He didn't know the answer when He asked the question, if He had had doubt, then the scene becomes a pathetic whimpering by our Lord and Savior, depending on whether this numbskull Peter was convinced enough by what He had said in the Bread of Life Discourse. That's just not what happened here. Peter is not the hero in this passage, Jesus is.
