Perhaps but only through a dream or vision. (Numb. 12:6) When Einstein was asked if he was an atheist, he answered and said, "Absolutely not! But, I can't think of God relating to man on a personal basis." Now, Satan is only a concept to illustrate the evil inclination in man. Therefore, an emanation and not a personal being. Metaphorically, yes, God and Satan speak to us all within ourselves.
