Dilexit Nos: On the Human and Divine Love of the Heart of Jesus Christ
123 In the first message that Saint Margaret Mary received, this invitation was expressed in vivid, fervent and loving terms. “He asked for my heart, which I asked him to take, which he did and then placed myself in his own adorable heart, from which he made me see mine like a little atom consumed in the fiery furnace of his own”.
