The Message of Merciful Love was received by Mamma Carmela during a period which lasted some ten years, from 1968 to 1978. It ended in the year that Rome had at last lifted the suspension on the Divine Mercy revelations to Sister Faustina, who was subsequently canonised by Pope John Paul II on April 30, 2000 in St. Peter's, Rome. In 1968, in the city of Milan, a widow with a large family, who had given her whole life to works of Mercy in her city, was praying one evening when she heard a voice that said: "You will be another witness to my Divine Mercy. I will bless you and give you special graces. I ask your help as a beggar asks alms. Will you help Me? I want you to find new apostles, and once again spread my message of Merciful Love to the ends of this earth." On March 22, 1970 Sister Faustina herself gave a message to Carmela and her Mother of Divine Love Prayer Group, she said: "It is not the first time that I come among you, but it is the first time that I wish to speak. I am Sister Faustina and I ask you to make with particular devotion the Novena of Mercy, so that all men will begin to believe in the mystery of salvation, which is contained in the devotion to the Divine Mercy."

Carmela Carabelli was born in Melegnano, Italy on May 9, 1910. She died in the peace of Christ on November 25, 1978. Since 1968 she received, almost daily, messages from Jesus Christ as the Merciful Jesus, and from the Blessed Virgin as the Mother of Divine Love. She transcribed straightaway into notebooks all that was said, without hesitation or correction afterwards, in the form of conversations with Jesus, who spoke about His Father, the Father of all men, and of His Mother, very tenderly; and so lovingly of his foster father St. Joseph, and about many other saintly people, and through this privileged person to all the world, for these writings are meant for all who wish to seek and find God.
