The book that the reader has in his hands is the fruit of years of theological reflection and spiritual. The first part contains the author's thinking about the topic of faith as a living and open heart attitude toward God. A text that has been woven over ten talks at length weighted between Santi Rovira and Pau Bertran Mosen, who has also been the editor. We listen to talk to two people trying simply "exercise the office of Christians" with the tools that each has. Always under "the fine rain" of the Word have prayed, they have pondered aloud, recalled the words in which they believe and have tried to find out why it can be so in love with the good news that Jesus came from eternity our time. The second and third part of the book include the works "divine language and human language" and "Faith under chapters 7 and 8 of the Gospel of St. John." Are two "meditative reflections" that constitute the subsidizes, ie, the theological foundations of reflections and insights that have emerged in the "dialogue" of the first part. Thus, this work becomes a sketch of spiritual theology for the XXI century.
