Saint Therese of Lisieux:

Christmas Eve in 1886 was a major turning point in the life of Therese, often called her "conversion night" at fourteen. Years later she stated that on that night she overcame the pressures she had faced since the death of her mother and said that "God worked a little miracle to make me grow up in an instant" on that night. Years later she said: "On that blessed night...Jesus who saw it fit to make Himself a child out of love for me, saw it fit to have me come forth from the swaddling clothes and imperfections of childhood."[16]

Before she was fourteen, when she started to experience a period of calm, Thérèse started to read The Imitation of Christ. She read the Imitation intently, as if the author traced each sentence for her: "The Kingdom of God is within you... Turn thee with thy whole heart unto the Lord; and forsake this wretched world: and thy soul shall find rest."[21] She kept the book with her constantly and wrote later that this book, and a book of a very different character, lectures by an Abbé Arminjon on The End of This World, and the Mysteries of the World to Come, nourished her during this critical period.[22] Thereafter she began to read other books, mostly on history and science.[23]
Jesus, Your ineffable image is the star which guides my steps. Ah, You know, Your sweet Face is for me Heaven on earth. My love discovers the charms of Your Face adorned with tears. I smile through my own tears when I contemplate Your sorrows"

"Love proves itself by deeds, so how am I to show my love? Great deeds are forbidden me. The only way I can prove my love is by scattering flowers and these flowers are every little sacrifice, every glance and word, and the doing of the least actions for love."
I see that it is enough to recognize one's nothingness and to abandon oneself, like a child, into God's arms. Leaving to great souls, to great minds, the beautiful books I cannot understand, I rejoice to be little because 'only children, and those who are like them, will be admitted to the heavenly banquet'."
"For me, prayer is a movement of the heart; it is a simple glance toward Heaven; it is a cry of gratitude and love in times of trial as well as in times of joy; finally, it is something great, supernatural, which expands my soul and unites me to Jesus. . . . I have not the courage to look through books for beautiful prayers.... I do like a child who does not know how to read; I say very simply to God what I want to say, and He always understands me."
