Many Catholics are familiar with Jesus’ private revelations to St. Margaret Mary Alacoque in 1673-1675 to propagate devotion to his Sacred Heart, but did you know our Lord also revealed 12 promises to those who honor him in this way?

Jesus said: I will give them all the graces necessary in their state of life; I will establish peace in their homes; I will comfort them in all their afflictions; I will be their secure refuge during life, and above all, in death; I will bestow abundant blessings upon all their undertakings; sinners will find in my heart the sources and infinite ocean of mercy; lukewarm souls shall become fervent; fervent souls shall quickly mount to high perfection; I will bless every place in which an image of my heart is exposed and honored; I will give to priests the gift of touching the most hardened hearts and those who shall promote this devotion shall have their names written in my heart.

The 12th promise is sometimes called the “great promise” and reveals the excessive mercy of Jesus’ loving heart.
