In the apparitions to St. Margaret Mary Alacoque, Jesus gives these twelve promises for those who are devoted to His Sacred Heart.
The Twelve Promises of Jesus to Saint Margaret Mary for those devoted to His Sacred Heart:
I will give them all the graces necessary for their state of life.
I will establish peace in their families.
I will console them in all their troubles.
They shall find in My Heart an assured refuge during
life and especially at the hour of their death.
I will pour abundant blessings on all their undertakings.
Sinners shall find in My Heart the source of an infinite ocean of mercy.
Tepid souls shall become fervent.
Fervent souls shall speedily rise to great perfection.
I will bless the homes where an image of My Heart shall be exposed and honored.
I will give to priests the power of touching the most hardened hearts.
Those who propagate this devotion shall have their names written in My Heart, never to be effaced.
The all-powerful love of My Heart will grant to all those who shall receive Communion on the First Friday of nine consecutive months the grace of final repentance; they shall not die under my displeasure, nor without receiving their Sacraments; My heart shall be their assured refuge at that last hour. “Look at this Heart which has loved men so much, and yet men do not want to love Me in return. Through you My divine Heart wishes to spread its love everywhere on earth.”
