Where is it written that God knows one’s future free will decisions? I can see where God can know many future things, because they are products of cause and effect. And I have heard the arguments that God is outside of time, but they don’t convince me. **To me God is in one point of time, the present. ** Without the created universe, in would not be called a point in time, just Beingness. But because there is time, we can call it the present, some say, the eternal present. I can also see that God can calculate with eerie accuracy what our free will decisions will be, but that is by educated guess, not absolute knowledge. I stand unconvinced that God, who knows all things, knows future free will decisions. God does know all things, but the future is not an existent thing. The future does not exist-- when it does exist, it is not called the future, it is called the present. God is only present to the present, the eternal present, since the future and the past do not exist except as ideas, not actualities.
Actually, I would argue that your bolded statement above is the problem. You are reducing eternity to “the present moment.” That is not what most classical theists, and, in particular, not Thomists, would claim. It is not that only the present moment is “eternal,” but that from the perspective of eternity all temporal moments (past, present and future) simply are.
The only reason things seem to go out of existence (past) or potentially come into existence (future) is because we, in the present, have a limited temporal view or “scope” of the entire process. An eternal view would give access to all past, present and future events as a malleable “whole.” God’s eternal (not constrained by time) existence would allow him to alter past events with reference to future events, which is why there appears to be, to us, a “dynamic” aspect to the present. The present is our own dynamic “point of contact” with the eternal which will “blend into” the eternal as a final outcome.
Thus, the sacrifice of lambs in the OT makes sense only with reference to the sacrifice of the Lamb, Christ, and that only makes sense with reference to the final end or “purpose” for which it had to occur which will only be clear at the end of the narrative. The reason things are not clear and not understood at this moment is because they can only gain full clarity when the end for which they are occurring has reached finality.
We operate under a kind of false, pseudo scientific, notion that the past explains the future. That the key to understanding what will happen is to replicate and control what is happening or will happen by looking serially back at patterns of events that have happened and using that knowledge to create the future.
This is not the way God works, however. He alters the past, present and future with regard to the teleological end and can effect anywhere along the timeline to make adjustments as necessary. In other words, he can account for our “free willed choices” because the entire story is open to him. It is being written in “eternity,” not in “the present” in ways we cannot even begin to comprehend.
The “danger” for us (but not for God) is in reducing God’s power to our views about that power. The reason that is a danger is because we succumb to the notion that our choices make no difference when, in fact, they are the very fabric of what God works with in “writing” the story.
