Nothing in this world is necessary to God or can rouse his desire. I am mistaken: there is one thing only that God desires ardently. He does everything to obtain it. What he wants is to find in the heart of man a centre always ready, that is to say, void of all else, so that he can accomplish in it and perfect in it his own work. Doubtless he rules with full authority over heaven and earth: nothing can resist his will; yet he seems to knock powerlessly because he is unable to carry out in the soul the work that he so loves and desires.
