The Trinity is not a puzzle to be explained. It is a model that enables us to talk about our experience of God. We might view the model as God above me, God beside me, God within me. And obviously those are not literal statements. We have chosen the spatial dimensions of ordinary geometry to give us metaphors for three aspects of our faith.
Many people feel like orphaned children in a scary world.
If they can run to God as parent, they feel safe, loved, comforted. I have calmed and quieted my soul, like a weaned child with its mother. Faith is knowing it is safe to play and explore our world. Faith then grows by learning the language of childlike faith. At first we can only cry and scream, but slowly we pick up the proper words to ask for help, define our needs, express the directions of our longings.
