Nope, you all still barking up the wrong tree. The problem is with the concept of
sustaining cause - and it is a purely logical question. Let’s get to the details.
A human with free will decides to perform an act. Whether it is shooting someone, or baking a loaf of bread, it does not matter. To carry out his decision, he needs to manipulate matter. But the matter would simply flicker out of existence, if God would not
actively sustain it. Therefore God’s action - to maintain the matter (the bullet on its trajectory, or the bread forming from the ingredients) - is
contingent upon our decision. Since God is “simple”, if his action is contingent, then God himself is contingent - which is contradicted by the concept that God is sovereign.
As I said, the problem is simply a logical one. If we are the primary causative agent, and God actively maintains the matter, then God’s action is contingent.
The problem is the “sustaining cause”. If one starts with the assumption that God created the universe
AND all the laws of nature, then there is no need for the constant “maintenance”. The ball keeps rolling according to laws created by God, and then only a minimum of interference is needed, when God decides to perform a miracle. So God is NOT contingent upon our actions any more.
That was the contradiction I presented. I was interested if anyone can figure it out.
