In a world governed by doubt, confusion and moral inconsistency, human beings continue to face the most profound and challenging questions: Does God exist? Who is he really? How can we reach him? Is the existence of suffering and evil compatible with the idea of divinity? In the majesty of some temples, in the notes of a symphony or in the beauty of some verses... we can find God anywhere, but then... why does religiosity seem to vanish in today's world? This book is a beacon in the darkness of uncertainty, which tries to respond to the concerns that have stirred the consciences of both believers and skeptics since ancient times. Its pages take us deep into the essence of spirituality, and explore the imprint of the divine in the history, art or thought of different cultures and corners of the world. “Who is God?” invites us to an open dialogue with the sacred in order to reflect on the transcendental questions that underpin our very existence: the role of God in our time, the reasons for believing in Him in the face of prevailing scientism... and, above all, how to prepare the heart for an encounter that could change everything.
