Devotion to the Sacred Heart is a powerful little booklet filled with many of the treasures to be found in the veneration of the Sacred Heart of Jesus. Besides containing an explanation of the symbolism found within the Image of the Sacred Heart, it also includes explanations of the 9 First Fridays devotion, known as the Great Promise, and the miraculous cure of St. Gemma Galgani, as well as many profound exhortations to offer reparation to the Sacred Heart.Our Lord instituted this authoritative and moving devotion Himself, saying, "I set neither limit nor measure to My gifts of grace for those who seek them in My heart."In our age of religious indifference, when fervor and charity have grown cold, Jesus exhibits to the world His Sacred Heart as the symbol of God's infinite love showing His Divine Heart as a furnace whose burning rays of love are able to reanimate faith and rekindle love in hearts grown cold and ungrateful.
