God communicates in strange and mysterious ways Rich; Moses who drew near to the thick darkness where God was, or the “still small voice” in the theophany to Elijah. I think you are quite right in saying that listening to the poor, the outcast and the powerless of this world is listening to the unheard voice of God, if we see in these people the figure of Jesus the Forgiving Victim. I think that unheard voice can also be an experience that seems quite unimportant until we realise later that it has been life changing. It can happen in so many different ways.
