God is omnipotent or not. If he is, he knows and has predetermined our choice, and he knows and allows the outcome and our lives are predestined and it is not a choice for he knows what has/is/will happen and has approved it all. To change it would admit to err.
If he allows free will and does not know, or chooses not to know what we will choose, or does not know the outcome of our choices, then he is not omnipotent, therefore, not a God.
