The Eighth Promise to those who faithfully pray the Rosary is that they shall have during their life and at their death the light of God and the plenitude of His graces. They will share in the merits of the blessed.
Saint Padre Pio, Saint Dominic, San Martín de Porres, Santa Teresa de Ávila, Saint Bernadette, San Juan de la Cruz, Mother Teresa of Calcutta, Saint Therese of the Child Jesus, Venerable Fulton Sheen, John Paul II and many other holy followers of Jesus, devoted so much of their prayer lives to contemplation of the life and virtues of Jesus. They understood the immense spiritual value of praying the Rosary. Their lives were exemplified by constant humility, unwavering trust, and courageous evangelizing, especially at times of vehement opposition to their faith. Like Mary they lived in obedience and surrender to God's will.
