Did Moses know anything about God when revealed to him in the Burning Bush??? Does not appear to me that he did. When God chooses a leader, he equips them for the task he was chosen to do.
I have observed a change in the countenance of Trump. He still has some rough and raw edges, but I can see that he has been changed . . . maybe some by his travails . . . maybe some by the influence of God leading him . . . but there is no doubt in my mind he is a changed man.
Good point.
