God’s responsibility for creation is a governing responsibility. Consider creation as an open system within a closed system. God could have created a world in which everyone never sinned, but that world may not have been feasible. God is responsible in causal sustaining sense as well, but that’s different from an actualizing sense. God weakly and strongly actualizes every state of affairs. As Plantinga defines the terms: God weakly actualizes S iff there is an S* such that God strongly actualizes [direct causation] S* and S* → S, where → is “counterfactual implication” (Let S be a state of affairs).
So am I free to break the predicted pattern? Well, the future is going to happen necessarily, but only because it will be a result of what we would do. Remember, God’s foreknowledge is a reflection of what we would do. In order to have an answer to that question, it depends on what I would do in whatever circumstance, that free choice will determine what will happen. In the words of William Lane Craig, “If God simply foreknows that man will sin, then it’s too late, so to speak, to do anything about it, since it’s logically impossible to change the future.” That’s why simple foreknowledge and Arminianism fails in my opinion. For further elaboration see why I’m not an Arminian. So is God responsible for everything in creation? Yes, but that does not include Goddetermining everything in creation.
In the words of C.S. Lewis, “If God thinks this state of war in the universe a price worth paying for free will…then we may take it it is worth paying.” (Mere Christianity)
