God is not physically present in the way our family or friends are, and that can be a stumbling block to faith. He cannot be seen, touched, heard or felt in person, and believing in something not tangibly present can be an obstacle to someone who is struggling. But I was thinking last night about the ways in which we do, in fact, use our senses to interact with him, and just as importantly, how he uses our senses to interact with us. Faith is not a one way street, it is a relationship, an interaction, a correspondence with our God, and it goes in both directions, if we open our senses to him.
