Divine Substance constitutes the third volume of interviews given by Yvonne Trubert for the Book of Invitation to Life, internal journal of the non-profit association Invitation to Life. Through themes such as Drugs and Alcohol, Depression, Adolescence and Relationships, Yvonne Trubert proposes elements of contemplation that vary from daily life to the most complex questions about one's destiny. Throughout, two subjects dominate : the power of love and divine presence.
These chronicles are directed to those who are in a quest for the absolute and to those who embark on this extraordinary journey with the goal of reuniting the once broken link between God and His Children. Thus, Yvonne Trubert invites her readers to understand that "God wanted to put his substance in our galaxy and that He created the costume that best fits this substance : humanity."
