It is unanswerable because it assumes a state of affairs that does not exist. I am not beating my wife and so I cannot stop. The utterly self-determined character of an everlasting God is the endpoint of all our questions. There comes a point when you stand face to face with absolute reality and realize that he simply is who he is. WHO I AM is that God does not change.
People change their mind because of unforeseen circumstances or weak resolution.
God foresees all circumstances and has no weaknesses. Nothing in all creation takes him off guard and backs him into a corner where he might have to act out of character or compromise his integrity. He is the same yesterday, today and for ever. His absolute name is the granite foundation of our confidence in his ongoing faithfulness. WHO I AM is that God is an inexhaustible source of energy.
