I had a Facebook friend overnight put up this statement:
You can’t have free will if God knows what you are going to do, before you do it.
The thing to remember here is that God exists outside of Time, which is a human construct. Therefore, Free Will vs Divine Omniscience becomes a frame of reference issue.
The classic frame of reference example is to look straight out of a train window. You see objects moving, which to you indicates that they are moving and that you are standing still. They, however, see a train moving and that they are standing still.
Which is correct?
It depends on your frame of reference. 😀
Similarly, the issue of Free will vs Divine Omniscience is also a frame of reference issue. Humans can accurately see, and thus know, only the present and past – much like a 180 degree camera on a train that is pointed towards the back of the train. It can see absolutely everything from its point on the train and backwards, but will never see towards the front of the train. Let us further assume that this camera is mounted on a horizontal rack and can move freely across the train side to side.
While the camera is free to move about horizontally all it wants, it will never see the front of the train, no matter how hard it tries. It will only get different views of its present and past, which may dictate the position it choose to be in next. But even in its next position, it will never see the front of the train.
God, however, exists independently of the train, and can see the entire train at once. Thus, He can see what the camera cannot. He can point things out behind the camera and beside the camera, and thus help to point the camera to the next best position, but He will always know exactly what the front of the train looks like, while the camera will not.
Thus, because of frames of reference in regards to Time, Free Will and Divine Omniscience can, indeed, co-exist.
