How does man end up negotiating with God?
Human reasoning cannot account for it. God, who knows everything, has already determined the most effective, just and reasonable course of action in every conceivable instance. He needs no advice or input from humanity. There is absolutely nothing created beings can contribute to the process by which a sovereign God works out his sovereign will. The idea is preposterous.
And yet it happens all the time in scripture. God deliberately seeks out man’s opinion, or else man expresses it and God allows him to have his say, even indulging his choices.
