God is eternal. Outside time. Never changing. Perfect. To be perfect God must be a simple substance. Pure act. No potency. God cannot change in any way because change necessarily implies motion (in the philosophical, Aristotelian sense) . Since God lacks potency, He cannot logically change.

To ascribe "Changing his mind" to God is simply an anthropomorphization of God and a category error.

Uh-oh. For someone who recognizes the trap of anthropmorphization, I think you've fallen into the related, subtler trap of reification. To say God is "pure act", or as some others claim "pure thought", is like saying God IS the number 9. Or "God is love". Either way it's a floating abstraction, unrelated to anything concrete. You can't get to a concrete entity - like a conscious personality which God supposedly is - from a floating abstraction. You need more; something physical. Otherwise, as you point out, God is incapable of moving atoms around.

But it's worse than that. It not only implies that God couldn't perform miracles, but it implies He couldn't create the physical universe to begin with, and neither could He even form the idea of creating the physical universe! How would such an idea be sustained? There's nothing like a neural network to hold the thoughts. And something within God has to change in order for the new thought to even exist. You can't just claim that God forms a thought without implying that there's some embodiment somewhere whose shape or form or state changes in order to hold the new information inherent in this thought.

An unembodied god is metaphysically static, & therefore powerless & trivial. Vacuous.

Were it not for the existence of sin in the world, says Calvin, human beings would believe in God to the same degree and with the same natural spontaneity displayed in our belief in the existence of other persons, or an external world, or the past. This is the natural human condition; it is because of our presently unnatural sinful condition that many of us find belief in God difficult or absurd. The fact is, Calvin thinks, one who does not believe in God is in an epistemically defective position-rather like someone who does not believe that his wife exists, or thinks that she is a cleverly constructed robot that has no thoughts, feelings, or consciousness. Thus the believer... reverses---Freud and Marx, claiming that what they see as sickness is really health and what they see as health is really sickness.

We know God from His effects, just as we know the existence of other human minds from their effects. We do not understand other human minds in themselves.
