The man who does not permit his spirit to be beaten down and upset by dryness and helplessness, but who lets God lead him peacefully through the wilderness, and desires no other support or guidance than that of pure faith and trust in God alone, will be brought to the Promised Land. He will taste the peace and joy of union with God. He will, without “seeing,” have a habitual, comforting, obscure and mysterious awareness of his God, present and acting in all the events of his life.
The man who is not afraid to abandon all his spiritual progress into the hands of God, to put prayer, virtue, merit, grace, and all gifts in the keeping of Him from Whom they all must come, will quickly be led to peace in union with Him. His peace will be all the sweeter because it will be free of every care.
Just as the light of faith is darkness to the mind, so the supreme supernatural activity of the mind and will in contemplation and infused love at first seems to us like inaction. That is why our natural faculties are anxious and restless. That is why they refuse to keep still. They want to be the sole principles of their own acts. The thought that they cannot act according to their own spontaneous impulsion brings them a suffering and humiliation which they find it hard to stand.
But contemplation lifts us beyond the sphere of our natural powers.
When you are traveling in a plane close to the ground you realize that you are going somewhere: but in the stratosphere, although you may be going seven times as fast, you lose all sense of speed.
As soon as there is any reasonable indication that God is drawing the spirit into this way of contemplation, we ought to remain at peace in a prayer that is utterly simplified, stripped of acts and reflections and clean of images, waiting in emptiness and vigilant expectancy for the will of God to be done in us. This waiting should be without anxiety and without deliberate hunger for any experience that comes within the range of our knowledge or memory, because any experience that we can grasp or understand will be inadequate and unworthy of the state which God wishes to bring our souls.
