We cannot be sure if we are loving God, although we may have good reasons for believing that we are, but we can know quite well if we are loving our neighbor. And be certain that, the farther advanced you find you are in this, the greater the love you will have for God.
Teresa of AvilaThe devil put before me that I could not endure the trials of the religious life, because of my delicate nurture. I defended myself against him by alleging the trials which Christ endured, and that it was not much for me to suffer something for His sake; besides, He would help me to bear it.
Teresa of AvilaTo reach something good it is very useful to have gone astray, and thus acquire experience.
