When you talk to God or engage in prayer, do you typically do it aloud or silent? I've noticed that almost everytime I find myself talking to God I'm doing it silently. I only remember a few times of actually speaking out loud. Is this okay? I don't remember ever reading whether you were supposed to do it one way or the other. I'm pretty sure God can still hear your prayers even though they are only being spoken in your head, right?
