Description: Ours is an age of lost illusions. Crises mount, perspectives blur, and points of reference vanish. Rightly or wrongly, in this world fraught with challenges, we worry about tomorrow. In this context--as possibilities dwindle--hope is crucial. Our life stories require us to cross many thresholds and navigate fears, grief, and impasses. Yet it is hope that enables us to remain standing, even through the night, like a watchman awaiting the dawn. In this work, Emmanuel Durand invites us to reconsider--through the prism of hope--the central mysteries of the Christian faith: God, creation, Christ, the Holy Spirit, charity... For him, hope in God is vital in those moments of darkness when salvation can no longer be envisioned.
