Can prayer change God's perfect plan?

[Aroura]

Right, I personally agree it is all predetermined, but I'm trying to talk to CL starting from her point of view.  I'm trying to point out the logical inconsistency in her argument.  Sometimes that means I discuss, for the sake of argument, things that I don't agree with or believe in, like God or free will.  
We all talk about God did this or God did that in here, even though we don't believe in him.  Same thing here.

I'd like her to answer my question.

I appreciate it. 

Though I feel like I've already answered that question and given my explanations. I'm not sure how else I can say the same thing.

Ok, let me try again.

"Explain to yourself first, and then anyone here, how anything is free if it cannot be any other way because the outcome is already known by God."

So far, you're explanation is simply that God stands outside of time and space, but this does not even begin to answer the question, that only explains HOW he experiences all things (and not very well at that), it does not address at all how that gives you or anyone free will.  You've simply sidestepped the question, not answered it.

For instance, right now, you have the "choice" to respond to me or not.  God already knows which way that will be.  How are you choosing it, then?  Can you possibly CHOOSE the other way that God has not forseen?? 

If the answer to the underlined is no, then how is this a choice at all?
