If he does or if he doesn't, the outcome is already known to God. It isn't known to him. You don't have to will yourself to believe for the sake of believing. You can choose not to believe. You are free to make that choice for yourself. God knowing what you will do in no way limits your ability to freely make your own choices. You are trying to apply the rules that men live by to God, it doesn't work very well. His time and our time are different.
