Of all beings on Earth, only humans are conscious of their mortality. The entirety of human life is oriented towards death. Despite this awareness, the precise timing and manner of death remain unknown, shrouded in an enigmatic mystery. This inherent uncertainty engenders latent anxiety and discomfort within the human psyche, which individuals persistently seek to comprehend and overcome. Death has been a perennial theme in many sciences, especially in humanistic discourses. This study illuminates death from three distinct perspectives: theology, psychology, and philosophy (existentialism). While these perspectives may differ, they all converge upon the singular and universal reality of death. Through an analysis of the biblical understanding of death, including its necessity and purpose, the author endeavors to reconstruct this elusive phenomenon, which finds its ultimate and complete realization in the person of Jesus Christ. The author then explores the various stages that palliative care patients go through as they approach the inevitability of death and delves into Frankl's role in shaping these moments, along with his perspective on death and, consequently, life. The work concludes with a reflection, drawing heavily on the philosophical insights of Heidegger and Kierkegaard, on the nature of an authentic life, which is achieved only through embracing one's mortality and limitations and making a conscious choice to live a life of faith.
