The Heart of Jesus is the symbol of the infinite love that impelled the Son of God to become our brother, to die for us on the Cross, and to remain forever in the Sacrament of the Altar. Jesus asks each of us to return that love.

In various appearances to St. Margaret Mary Alacoque, Jesus manifested His great love for human beings and made the following promises to those who give particular honor to His Sacred Heart:

1. "I will give them all the graces necessary in their state of life."
2. "I will establish peace in their homes."
3. "I will comfort them in their afflictions."
4. "I will be their secure refuge during life, and above all in death."
5. "I will bestow a large blessing upon all their undertakings."
6. "Sinners shall find in My Heart the source and the infinite ocean of mercy."
7. "Tepid souls shall grow fervent."
8. "Fervent souls shall quickly mount to high perfection."
9. "I will bless every place where a picture of My Heart shall be set up and honored."
10. "I will give to priests the gift of touching the most hardened hearts."
11. "Those who shall promote this devotion shall have their names 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 communicate on the First Friday in nine consecutive months, the grace of final penitence; they shall not die in My disgrace nor without receiving the Sacraments; My Divine heart shall be their safe refuge in this last moment."
