The Devotion to the Sacred Heart is one of the most widely practiced and well-known Catholic devotions, wherein the heart of Jesus is viewed as a symbol of "God's boundless and passionate love for mankind".
Jesus revealed 12 promises to St. Margaret Mary Alacoque for those who will honour the Sacred Heart of Jesus.
1. I will give them all the graces necessary for their state in life.
2. I will establish peace in their families.
3. I will comfort them in their trials.
4. I will be their secure refuge during life, and, above all, in death.
5. I will shed abundant blessings on all their undertakings.
6. Sinners will find in My Heart an infinite ocean of mercy.
7. Lukewarm souls will become fervent.
8. Fervent souls will rapidly grow in holiness and perfection.
9. I will bless every place where an image of My Heart shall be exposed and honoured.
10. I will give to priests the gift of touching the most hardened hearts.
11. The names of those who promote this devotion will be written in My Heart, never to be blotted out.
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.
