That's exactly what it means, IF that "one outcome" can be known before the choices are made.
Because that can only be the case if the choices in question aren't actually free.
If it can be known beforehand that I will order chicken instead of steak, then I was never "free" to order steak instead.
Instead, I was actually compelled (by whatever) to order chicken. At best, I was only under the illusion that I choose that freely.
Explain how God's knowledge of what we will do in the future compels us to do anything.
You were free to order either chicken or steak.
God knows beforehand if you will order chicken instead of steak, but if you had ordered steak instead of chicken, that is what God would have known you would do.
Not if it was known beforehand what the outcome was going to be. The point. You keep missing it.
If it can be known with certainty beforehand that you will choose chicken, and if that knowledge can't be wrong, then you were never free to choose something else.
Then choosing chicken was a compulsion and the idea that you choose it freely was only an illusion.
If it can be known with certainty beforehand that you will choose chicken, and if that knowledge can't be wrong, you will choose chicken, but BEFORE you chose chicken you could have chosen steak instead, and in that case it would have been known by God that you would choose steak.
Correct.
BEFORE you make the choice, there are two POTENTIAL outcomes.
And BEFORE you make the choice, there is UNCERTAINTY which of the two POTENTIAL outcomes will become the ACTUAL outcome.
Correct.
However, if there is such a thing as "perfect foreknowledge" that it's going to be red, then BEFORE you chose, there already was only ONE possible outcome: red.
Your choice thus is no longer free. It's already determined to be red (by whatever). It has to be, otherwise it couldn't already be known that it was going to be red.
The perfect foreknowledge is of whatever you will choose.
You are free to choose a red shirt or a blue shirt.
If You had chosen a red shirt that is
what God would have known you would choose.
If You had chosen a blue shirt that is
what God would have known you would choose.
What God knows is contingent upon what you will choose and it is identical with what you will choose.
Either there are two possible outcomes before you chose and there is free choice
or
There is only possible outcome before you chose and there is NO free choice.
You can't have it both ways.
There are two possible outcomes
before you chose and there is free choice.
If there was only on possible outcome it would not be a choice. You would be a programmed robot.
Imagine going to court and telling the judge that you don't have a choice because God knew you would murder your wife. See how that flies.
If you had chosen to murder your wife and carried that out God would has known you would choose that action because God is all-knowing.
If you had chosen not to murder your wife and carried that out God would has known you would choose that action because God is all-knowing.
It is really as simple as that.
