What are the 12 promises of the Sacred Heart devotion?

In 1673, a French Visitandine (Visitation) nun named Margaret Mary Alacoque had a private revelation of Jesus, in which he asked the Church to honor his Most Sacred Heart.

In particular, Jesus gave to St. Margaret Mary 12 specific promises made to all who venerated and promoted devotion to the Sacred Heart.

Jesus said to St. Margaret Mary, “Behold the Heart which has so loved men that it has spared nothing, even to exhausting and consuming Itself, in order to testify Its love … I promise you that My Heart shall expand Itself to shed in abundance the influence of Its Divine Love upon those who shall thus honor It, and cause It to be honored.”

The entire purpose of this devotion is to draw a person closer to the heart of Christ. If a person spreads devotion to the Sacred Heart, it is natural for him or her to be closer to God. The moment that this devotion is observed in a superstitious manner, neglecting the need to live a virtuous life, all bets are off and Jesus’ promises are null and void.

Jesus wants us to rest on his heart, like St. John, and the Sacred Heart devotion is an opportunity for us to encounter him more than just on Sundays and to deepen our love of him.

• Sinners will find in my heart the source and infinite ocean of mercy.

• I will give to priests the gift of touching the most hardened hearts.
• Those who shall promote this devotion shall have their names written in my Heart.
• I promise you in the excessive mercy of my Heart that my all-powerful love will grant to all those who receive Holy Communion on the First Fridays in nine consecutive months the grace of final perseverance; they shall not die in my disgrace, nor without receiving their sacraments. My divine heart shall be their safe refuge in this last moment.
