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. We were of course hearing expressions of love from the first day in our parents' arms, but understanding what they had in mind took many months of language learning. Parents were limited to a few words, and looks, and hugs, and kisses, but Trinitarian faith is discovering that God the Father above us is speaking the language of love through every one of our senses in hundreds of different ways every day. People also talk to God as a friend beside them. We can say things to a friend which we might not share with our parents.
