Unless you can see a past where the other choice was made you have no evidence of it even existing.
I call heaven and earth to record this day against you,
that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: Deuteronomy 30:19
To you it would be unfair that we were not allowed to see the future to determine the best possible choice.
Unless you actually meant "It would be unfair to you" instead of the way you stated it which suggests I would complain that it was unfair... I would say:
Baloney. I never even implied such a thing. If you want to do some gun-spiking go right ahead but let's not fancy ourselves mind-readers. God-given reasoning will suffice in trying to make the best decision to my satisfaction. In any case, how could it be unfair if the same rules applied to everyone?
Is free will truly the solution the problem you have with God?
Free will isn't designed to solve any problem. It is simply a characteristic of all created beings with reasoning powers.
And if by "problem" you mean the natural enmity toward God in sinful human nature then
Christ and Him crucified would be the solution. Boy oh boy we're really doing some dancing here aren't we?
How is it just that we are only given a partial view of the situation?
Because that's all we need to make the best possible decision under the circumstances.
If we are truly to be held according to our choice then is choice masked by ignorance truly free?
The Bible says God winks at ignorance.
How is it just when we are not able to choose the best possible option every single time?
Because we are only required to make the best possible decision under the circumstances.
Swing your partner. Promenade.
Free will solves none of these problems.
Again, free will is not intended to solve any problems. Especially imaginary ones.
The Bible clearly states predestination
It does no such thing unless the entire Bible is to be read through the lens of an all-or-nothing cognitive distortion of Romans 9.
What the Bible clearly does is to dispute nearly every sentence of your post quoted here.
...and also proves the character of God when he sent his one and only son to die for sinners. God is perfectly just in his actions and is a sovereign being.
No argument there. Amen and Hallelujah, Brother!
So once again the argument in favor of determinism raises more questions than solutions.
