Now faith actually brings all of the unconscious into integration with the rest of our life, but it does so in different ways. What is below us is accepted (not by any means merely rationalized). It is consented to in so far as it is willed by God. Faith enables us to come to terms with our animal nature and to accept the task of trying to govern it according to the divine will, that is, according to love. At the same time, faith subjects our reason to the hidden spiritual forces that are above it. In so doing, the whole man is brought into subjection to the “unknown” that is above him.
