Deepertruth: The 15 Promises Our Lady gave for the Rosary. The 15th Promise

15. Devotion of my Rosary is a great sign of predestination. Notice that the Virgin Mary states the Rosary is a "great sign" of predestination. This is our undertaking using free-will that we want to be saved. Our Lady promises that through the devotion of the Rosary, we are choosing our freedom to please Our Lord and Our Lady in the fight against darkness. Consider Ephesians 1:3-6, "Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavens, as he chose us in him, before the foundation of the world, to be holy and without blemish before him. In love he destined us for adoption to himself through Jesus Christ, in accord with the favor of his will, for the praise of the glory of his grace that he granted us in the beloved."
