I know this has been discussed here before, but it's been a while, and honestly I don't remember much of it. But I heard a man yesterday say something about prayers that don't go anywhere, that don't even leave the room and God doesn't hear them. My opinion is that God hears al prayers from His children, I mean do you ignore your children and not want to hear them, this does not mean God gives an affirmative answer to each prayer. By saying a prayer doesn't leave the room and God didn't hear it isn't that like shrinking God down, putting Him in a box. God is everywhere at all times, then wasn't He in the room and heard a prayer from one of His children.
