On the contrary, a spiritual life is the kind of life we were made for. It is full and real and free, yet with its own standards and laws. Physical life is founded upon constant interaction with our physical environment, we breath the atmosphere that surrounds us, we eat the plants and animals. We interact with other people. We touch and see and hear all that is going on around us.
Spiritual life is constant interaction with our spiritual environment.
To be fully human, we need both interactions, both physical and spiritual. But for most people, the presence and action of the great spiritual universe surrounding them is no more noticed than the pressure of air on their bodies. They work so hard developing their interaction with the visible world, that their power of interacting with the invisible is hardly developed at all. Horizons are widened, Experience is enriched, and at the same time responsibilities are enlarged. Here the creative action of God on a human creature enters a new phase.
