Mystical City of God, The Conception, Book 1, Chapter 2

The Venerable Sister Maria de Jesus of Ágreda describes how the history of the Blessed Virgin Mary was explained to her. The different types or modes of revelation she experienced and their grades or characteristics. She tells us of how she was born with a great grace – the fear of the loss of God. Seen by many as a weakness in faith, Maria tells us of how it is, “Her greatest blessing.”
