holiest works for sanctification of the soul
These promises were given to St. Margaret Mary Alacoque by Our Lord Jesus Christ for the sake of our souls. They are for those who devote themselves to the Sacred Heart of Jesus Christ. More can be read about this devotion and these promises in the book, 'The Autobiography of St. Margaret Mary Alacoque' which she wrote under obedience.
1. I will give them all the graces necessary for their state of life.
2. I will establish peace in their families.
3. I will console them in all their difficulties.
4. They shall find in My Heart an assured refuge during life and especially at the hour of death.
5. I will pour out abundant benedictions on all their undertakings.
6. Sinners shall find in My Heart an infinite ocean of mercy.
7. Tepid souls shall become fervent.
8. Fervent souls shall advance rapidly to great perfection.
9. I will bless the homes in which the image of My Sacred Heart shall be exposed and honored.
10. I will give to priests the power of touching the most hardened hearts.
11. Persons who propagate this devotion shall have their names inscribed in My Heart, and they shall never be effaced from It.
12. I promise thee in the excess of the mercy of My Heart, that Its all-powerful love will grant to all those who shall receive Communion on the First Friday of every month, for nine consecutive months, the grace of final repentance, and that they shall not die under My displeasure, nor without receiving their Sacraments, and that My Heart shall be their assured refuge at that last hour.
'The Heart of Jesus, contains the treasures of grace, and it is the Savior's Will to pour them forth on men through the medium of devotion to this Sacred Heart.'
St. Margaret Mary Alacoque
