"How do they know you're looking at their picture or praying to them? They aren't here, and you aren't there."
I don't know if they realize I'm looking at their picture or not. That has nothing to do with it. Who cares? It's just there as a reminder of who that person is. That's it! I don't have to have a statue of Mary in front of me to ask for her prayers. Sometimes, when I see a statue of her, I may choose to say a prayer right then. Not because I think it is actually her but because seeing it brought her to my mind. Just as seeing a picture of Jesus will bring him to the forefront of my mind.
Is Mary omniscient? omnipresent?
