Metanoia: A Catholic Book Series, Book Number Two: Prayer and the Tingling Grace is the author’s second publication in a series of Catholic books. In Prayer and the Tingling Grace, the author sets forth his experience with what he calls the tingling grace. The tingling grace is a “grace of prayer,” according to one of the author’s past confessors, a Carmelite priest. As such, it has most commonly been experienced by novice monks and nuns during prayer. However, according to the Carmelite priest, about five percent of lay Catholics also experience it. In the pages that follow, the author recounts his understanding of and experiences with the tingling grace, a sensible manifestation of actual grace given by a loving and guiding God to encourage the performance of salvific and salutary acts, such as prayer, frequenting the sacraments, spiritual reading, spiritual and corporeal works of mercy, and discernment of one's vocation. He is publishing it to testify or witness to God’s love, sanctification, and guidance of Catholics through this amazing grace, in light of the current crisis of faith, inside and outside the Church. Finally, this book is part of the author’s lay apostolate of Roman Catholic witness, as well as the author’s response to and promotion of the Church’s “universal call to holiness” (Lumen Gentium) and the “new evangelization” (Novo Millenio Ineunte), in the electronically and globally connected virtual world of the Internet.
