But how do you know either of those things are true?
Well, if God knows the outcome, can you do otherwise? That's exactly what I'm asking.
In other words, for example, does God know before you were born how your life will go, and whether you will be sent to Heaven or Hell upon your death? And if God knows these things, aren't they your fate? If you truly had free will, then God would not know the outcome until you freely decided it.
We know things are true by beginning with presuppositions, and then reasoning them out. So I had to start with the presupposition that God is omniscient, and you did not. Its as simple as that.
You are just restating the posit you made, and it doesn't get past your presupposition that God's omniscience doesn't exist if free will exists.( Its in your last statement in the post here.) I pointed out in the last post that God is not definable, or beyond our ability to define. So what you need to do is present an argument to me that God is definable, and not beyond our ability to define. And that is going to be tough for you, since a definable God is necessarily finite, and it is accepted God in eternal/infinite. So the onus is on you to show how God's omniscience is contrary to free-will.
