Spirit will speak to you in many ways.  Yes, at times the messages you need to hear come in a still, small Voice from within.  At others they come through external gifts.  Just the right person carries the perfect message.  A card reveals the answer you seek.  A sign along the road is the very sign you were looking for.  If you are the mouth and arms and legs of Spirit, if Spirit is not one being, but pure Being, itself, then Spirit speaks through all that is in limitless ways.  Be open to receiving the gifts of the Spirit.  You are here to claim the Kingdom, but this only happens as true understanding of your True Nature dawns.
