The years since the first publication of this work have not detracted from it, "for the role of religion in the lay States is the subject of vehement discussions in the times that are in Spain and in Europe, and behind these debates lies the deeper question of whether a modern and enlightened man can defend in the face of reason , and in what way, faith in God".
Hans Kong eludes both fideist naivety (with Descartes) and ideological rationalism (with Pascal), tackling the challenges of modern atheism (Feuerbach, Marx and Freud) and postmodern nihilism (Nietzsche). The result of both has been the questioning of fundamental certainties: those relating to religious faith and those concerning the consistency and sense of reality in general. This result is irrefutable, but at the same time inconclusive, for Kong. "Yes to reality", as an alternative to nihilism, from a position of radical trust; "yes to God", as an alternative to atheism, from a faith that transcends reason without denying it; and "yes to the God of the Bible", to the God of Jesus Christ in particular, as the foundation of that radical trust: such are the three basic stages by which Kong answers the title question of his work.
