An enthralling insight into how Christ uses Saint Faustina to reveal the divine mysteries of His merciful love for mankind. His purpose, as recounted in the book,is to enable the saint to glorify God through her life and co-operate with God's plan of redemption. Permitted to gain a vision of heaven, she notes in her diary: "O my God, how I pity those who do not believe in eternal life; how I pray for them that a ray of mercy would envelope them too, and that God would clasp them to his fatherly bosom."On prayer and sacrifice, Christ instructs us through Saint Faustina as follows: "You will save more souls through prayer and suffering than will a missionary through his teachings and sermons alone. You must be annihilated , destroyed, living as if you were dead in the most secret depths of your being. You must be destroyed in that secret depth where the human eye has never penetrated; then will I find in you a pleasing sacrifice, a holocaust full of sweetness and fragrance. Outwardly, your sacrifice must look like this: silent, hidden, permeated with love, imbued with prayer."The devotions are intended to perfect and strengthen our faith, and inspire in us God's strength and consolation to overcome all the spiritual and earthly challenges to our redemption. By these devotions God in His mercy makes actual in ourselves, through the Holy Spirit, the treasures acquired for mankind through Christ's sacrificial life.This is a book to be read, meditated upon, and lived.
