In A Heart on Fire: Rediscovering Devotion to the Sacred Heart of Jesus, Rev. James Kubicki, SJ, presents a persuasive and engaging guide to the Sacred Heart of Jesus, an age-old and often misunderstood Catholic devotion. He delves into the rich theological and spiritual roots of the devotion and demonstrates how the faithful may encounter the Sacred Heart of Jesus in one another, scripture, the sacraments, and especially in the Eucharist.

Fr. Kubicki, former national director of the Apostleship of Prayer (now the Pope's Worldwide Prayer Network), brings to life the rich imagery associated with the devotion’s history and provides a contemporary look at traditional devotions like the Twelve Promises, family consecration and enthronement, the Sacred Heart Badge, the Litany of the Sacred Heart, holy hours, and devotion to the Immaculate Heart of Mary.
