God does not offer himself to our finite beings as a thing all complete and ready to be embraced. For us he is eternal discovery and eternal growth. The more we think we understand him, the more he reveals himself as otherwise. The more we think we hold him, the further he withdraws, drawing us into the depths of himself.
