St. Paul of the Cross, Letter 594
“By God’s high providence, you find yourself struggling in darkness. That’s where humility and self-knowledge are found. So don’t give up prayer, interior solitude, acceptance of God’s Holy Will and all other virtues. Faith come alive in the dark. With love, then, detached from everything else, reach out to God in the silence and alone. Search for God carefully and peacefully.
But what am I saying? Isn’t God always with us? With naked faith, go to the depths of your soul and find your highest Good. Stay there and you’ll find all riches. We know that; remember it.”
