About the 12 Promises of Devotion to the Sacred Heart:  (12.) I promise thee, in the excessive mercy of My Heart, that My all-powerful love will grant to all those who receive Holy Communion on the First Friday of nine consecutive months, the grace of final penitence; they shall not die in My disgrace nor without receiving their Sacraments; My Divine Heart shall be their safe refuge in this last moment.
