The Servant of God Luisa Piccarreta was born in Corato in the Province of Bari, Italy on April 23, 1865 and died there in the odor of sanctity on March 4, 1947.
Luisa from her very birth was given a Mystical life, for example, at the age of 17 she received the Mystical Union that Saint John of the Cross, Saint Teresa of Avila and Saint Catherine of Siena received right before they died. After this Mystical Union Jesus asked Luisa if she would stay in bed and because of her Fiat!, He taught Luisa about the Life of the Divine Will forming It first in her.
For the next 64 years until her death Luisa stayed in bed basically not eating, drinking or sleeping. Luisa was nourished by receiving the Most Holy Eucharist during the Holy Sacrifice of the Mass daily said in her room. This special blessing was given by Pope Saint Pious X and Pope Leo XIII his predecessor. Luisa also lived on the food of the Divine Will, which Jesus said in the Gospels, a food that you do not know of .
During that time through great sufferings and a sublime call to holiness Jesus taught Luisa about the fulfillment of the Our Father, the prayer that Jesus taught His Apostles. "...Your Will be done on earth as in Heaven..."
Jesus taught Luisa that now is the time for the Kingdom of God to reign on earth as in Heaven. Jesus dictated 36 Volumes of the doctrine of the Divine Will, which He gave the title "The Kingdom of the Fiat in the Midst of Creatures. Book of Heaven -- The Recall of the Creature into the Order, to Its Place and into the Purpose for Which He was Created by God, to teach Luisa how to Live in the Divine Will, this is different than the devotional life of the Saints which is doing the Will of God.
In humble obedience Luisa under the constant direction of the Church faithfully wrote all that Jesus Himself wanted her to put down on paper. This would be not only for herself but for those who would read it, so that they too could Live in the Divine Will as Luisa learned how to Live in the Divine Will by putting into practice these Truths taught by Jesus and Mary.
In addition to the 36 Volumes Jesus dictated the book, The Hours of the Passion and Our Lady dictated the book, Virgin Mary in the Kingdom of the Divine Will to Luisa. Jesus told her Confessor, Saint Annibale Maria Di Francia, through Luisa that these 36 Volumes are to be called: The Book of Heaven.
Pope John Paul II canonized Saint Annibale and declared him to be the Saint for our time to pray to for Vocations. Yet, Saint Annibale himself stated in Messina on February 14, 1927:
Know that I no longer occupy myself with almost anything of the other things of my Institutes, since I dedicated myself completely to the great Work of the Divine Will. I talk about it with people of (docile) spirit; I engage in conversation about this topic with whomever I best can; I promote it as much as I can, even in my Institutes.
