That is not even close to what I said… not even in the same country…
I said that God’s knowledge of your final outcome is the result of your choices. He knows you die an atheist because you chose to remain an atheist until you die. Or, he knows you die a theist because you chose to become a theist before you die. Only one of these two potentials will be actualized, and the one that actually occurs is the one God has eternally known.
The reason you can’t change it (from an eternal perspective) is because it is the result of the sum of your choices in life, and once you’re dead you can change what your state was when you died. God does not prevent you from becoming a theist throughout your life, therefore causing you to be an atheist when you die. He gives you every chance to change up until the moment of your death, at which point your theist/atheist status is solidified, and cannot be changed.
I don’t see what’s so difficult about this for you to understand. When you die, you are either going to be an atheist or a theist. Which you are is the result of your choices. God, having knowledge of all of our choices, knows that you chose at the moment of death, and has know that eternally. If you die as an atheist, then God has eternally known that that is your state at death. If, on the other hand, you die as a theist, then God has eternally known that that is your state at death. Whatever God knows is the result of your final choice.
You will be one or the other at death, but you can only be one of the two. Whichever one of the two you are, God has been witness to your choice from all eternity.
Maybe this will help.
You keep talking about the “fact” of you dying an atheist. Well, that is only a fact if you die an atheist. If you die a theist, then the fact that God knows is that you die a theist. God cannot know you die an atheist if you actually die a theist. The choice is up to you, and God knows how you chose. Once you’re dead you cannot change it, but every moment preceding that death gives you the opportunity to convert.
Since God’s knowledge encompasses all of time, He is eternally witness to your choice at death, which is the source of His “current” knowledge of your outcome.
