The Holy Spirit brings the living, transfigured Christ into humanity. Thus does Christian interiority arise. This does not mean that one becomes profound in a mental sense: it means the opposite of squandering oneself in what is exterior. It implies that there is a depth in man in which Christ lives. It is possible to live with this Christ. He can become the very content of life. Then the New Man comes into being. The old man is the one he was before, but now the New Man is sown in him. How this happens cannot be described. It can be that certain persons experience this reality so powerfully that they can no longer feel at home in the world. This is how monasticism arose.
We seek the Lord in ordinariness, this is where Christ lives with us. If we are renewed at all, it is due to our availability, our attention to Christ's Spirit speaking to us in the depths of our hearts, calling us to ever deeper conversion. Our desire is total availability to his desire for us.
